The prizes, worth $20,000 each, are awarded in five areas: physics, chemistry, physiology or medicine, literature and economic science. Comin is the only recipient from the University of Toronto this year. (<a href="http://news.utoronto.ca/tags/polanyi-prize">Read about some of ³Ō¹Ļ±¬ĮĻ's previous&nbsp;Polanyi Prize winners</a>.)</p> <p>ā€œBy scientific upbringing, Iā€™m a solid state physicist,ā€ said Comin. ā€œI take new compounds, films or crystals, crafted by chemists, and I analyze them to figure out whatā€™s special about those materials.ā€</p> <p>Cominā€™s work, under the direction of Professor <strong>Ted Sargent</strong>, is to investigate the mysterious properties of a very special family of hybrid organic-inorganic materials called perovskites. Perovskites show great promise for a range of applications, from more efficient LED technologies to high-efficiency flexible and lightweight solar cells.</p> <p>Read more about Cominā€™s recent work, published in the journals<em> Science</em> and <em>Nature</em>:</p> <ul> <li><a href="http://news.utoronto.ca/new-technique-could-lead-cheaper-more-efficient-solar-power-and-leds">Crystal light: New family of light-converting materials points to cheaper, more efficient solar power and LEDs</a></li> <li><a href="http://news.utoronto.ca/fiat-lux-what-do-you-get-when-you-combine-perovskite-and-colloidal-dots">Engineered hybrid crystal opens new frontiers for high-efficiency lighting</a></li> </ul> <p>ā€œMy work in the Sargent Group has been to explore various key characteristics of perovskites, including their chemical composition, crystalline structure, and electronic structure,ā€ said Comin. ā€œThanks to the Polanyi Prize, I plan to expand my work into using x-ray methods to look at the collective phenomena involving the reorientation of the organic molecules embedded in the inorganic crystalline structure of these hybrid materials.ā€</p> <p>Comin earned his bachelorā€™s and masterā€™s degrees at the Universita degli Studi di Trieste in Italy, both in physics. He completed his PhD at the University of British Columbia under the supervision of Andrea Damascelli, where he worked on characterizing quantum materials. When he joined the Sargent Group for his postdoctoral fellowship, he was ready to take a more applied approach to his research.</p> <p>ā€œIā€™d done a lot of fundamental materials science, and I was thinking, ā€˜What are the strategies and processes involved in harnessing and functionalizing the material properties that are key for devices that realize solar, imaging or lighting applications?ā€™ā€ he said ā€œHere, weā€™re trying not just to develop high-quality materials, but also to combine them into device architectures that use the best properties of these materials. Ultimately, the metric for the quality of the work is the efficiency and performance of our devices.ā€</p> <p>The John Charles Polanyi prize was created in honour of the achievement of <strong>John Charles Polanyi,</strong> recipient of the 1986 Nobel Prize in Chemistry and a professor in the University of Torontoā€™s department of chemistry.</p> <p>ā€œMy congratulations to Riccardo, who is doing exceptional research,ā€ said Professor Sargent, vice-dean, research for the Faculty of Applied Science &amp;

I recently co-founded a biotechnology company that aims&nbsp;to save the oceans&nbsp;so I was very excited about this business learning opportunity.

I thought this was a great way for me to gain new experiences and learn outside of the classroom while earning one course credit. The IMC390 course allows students to gain work experiences with a startup while in school and Iā€™m fortunate to be able to contribute to the business development of such a cool green-tech company.</div> <div>&nbsp;</div> <div><strong>Does your work at Nanoleaf connect with or supplement what youā€™ve learned at ³Ō¹Ļ±¬ĮĻ?</strong></div> <div><strong>Yao</strong> Indirectly, yes. I am a science student a ³Ō¹Ļ±¬ĮĻ. My role at Nanoleaf is in business development. The two may not seem connected&nbsp;but definitely complement one another. The technical side of an idea or research project is essential but there are countless number of technicalities that could keep a person occupied. To be able to bring this research to the real world, there must be an appropriate market fit and strategic plan.

Perovskites are a family of materials that can be easily manufactured from solution, and that allow electrons to move swiftly through them with minimal loss or capture by defects.&nbsp;</p> <div style="float: left; margin: 5px 15px 10px 0; width: 300px"><img alt src="/sites/default/files/2015-07-17_DotsinPerovskite_Glowing1_square-300.gif" style="width: 300px; height: 300px;"> <p style="margin-top:0">A glowing quantum dot seamlessly integrated into a perovskite crystal matrix (Image: Ella Marushchenko).</p> </div> <p>The work was&nbsp;published July 15&nbsp;in <a href="http://www.nature.com/nature/journal/v523/n7560/full/nature14563.html">the international journal <em>Nature</em></a>.</p> <p>ā€œItā€™s a pretty novel idea to blend together these two optoelectronic materials, both of which are gaining a lot of traction,ā€ said&nbsp;<strong>Xiwen Gong</strong>, one of the studyā€™s lead authors and a PhD candidate working with Professor <strong>Ted Sargent</strong>. ā€œWe wanted to take advantage of the benefits of both by combining them seamlessly in a solid-state matrix.ā€</p> <p>The result is a black crystal that relies on the perovskite matrix to ā€˜funnelā€™ electrons into the quantum dots, which are extremely efficient at converting electricity to light. Hyper-efficient LED technologies could enable applications from the visible-light LED bulbs in every home, to new displays, to gesture recognition using near-infrared wavelengths.</p> <p>ā€œWhen you try to jam two different crystals together, they often form separate phases without blending smoothly into each other,ā€ said&nbsp;<strong>Riccardo Comin</strong>, a post-doctoral fellow in the Sargent Group.</p> <p>ā€œWe had to design a new strategy to&nbsp;convince these two components to forget about their differences and to rather intermix into forming a unique crystalline entity.ā€&nbsp;</p> <p>The main challenge was making the orientation of the two crystal structures line up, called heteroexpitaxy. To achieve heteroepitaxy, Gong, Comin and their team engineered a way to connect the atomic ā€˜endsā€™ of the two crystalline structures so that they aligned smoothly, without defects forming at the seams.</p> <p>ā€œWe started by building a nano-scale scaffolding ā€˜shellā€™ around the quantum dots in solution, then grew the perovskite crystal around that shell so the two faces aligned,ā€ explained coauthor <strong>Zhijun Ning</strong>, who contributed to the work while a post-doctoral fellow at UofT and is now a faculty member at ShanghaiTech.</p> <p>The resulting heterogeneous material is the basis for a new family of highly energy-efficient near-infrared LEDs. Infrared LEDs can be harnessed for improved night-vision technology, to better biomedical imaging, to high-speed telecommunications.</p> <p>Combining the two materials in this way also solves the problem of self-absorption, which occurs when a substance partly re-absorbs the same spectrum of energy that it emits, with a net efficiency loss.</p> <p>ā€œThese dots in perovskite donā€™t suffer reabsorption, because the emission of the dots doesnā€™t overlap with the absorption spectrum of the perovskite,ā€ Comin said.</p> <p>Gong, Comin and the team deliberately designed their material to be compatible with solution-processing, so it could be readily integrated with the most inexpensive and commercially practical ways of manufacturing solar film and devices.</p> <p>Their next step is to build and test the hardware to capitalize on the concept they have proven with this work.</p> <p>ā€œWeā€™re going to build the LED device and try to beat the record power efficiency reported in the literature,ā€ Gong said.</p> <p>This work was supported by the Ontario Research Fund Research Excellence Program, the Natural Sciences and Engineering Research Council of Canada (NSERC), and the King Abdullah University of Science &amp; Technology (KAUST).</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2015-07-16-LED-researchers.jpg</div> </div> Fri, 17 Jul 2015 10:07:14 +0000 sgupta 7153 at The organic LED age is here: Meet the ³Ō¹Ļ±¬ĮĻ engineers behind OTI Lumionics /news/organic-led-age-here-meet-u-t-engineers-behind-oti-lumionics <span class="field field--name-title field--type-string field--label-hidden">The organic LED age is here: Meet the ³Ō¹Ļ±¬ĮĻ engineers behind OTI Lumionics</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2015-02-25T05:08:02-05:00" title="Wednesday, February 25, 2015 - 05:08" class="datetime">Wed, 02/25/2015 - 05:08</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">The OLED research team (above photo by Mark Balson)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/robert-hercz" hreflang="en">Robert Hercz</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Robert Hercz</div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/lighting" hreflang="en">Lighting</a></div> <div class="field__item"><a href="/news/tags/startup" hreflang="en">Startup</a></div> <div class="field__item"><a href="/news/tags/entrepreneurship" hreflang="en">Entrepreneurship</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/commercialization" hreflang="en">Commercialization</a></div> <div class="field__item"><a href="/news/tags/features" hreflang="en">Features</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Google ā€œOLED,ā€ and youā€™ll find scores of articles confidently predicting that this is the year of the organic light-emitting diode. Some of those articles are ten years old.</p> <p>Still, there are reasons to believe the OLED age is finally dawning. In fact, engineering alumnus <strong>Michael Helander</strong>&nbsp;is betting on it.</p> <p>Three years ago, Helander&nbsp;was a PhD student with an important discovery just published in <em>Science&nbsp;ā€“&nbsp;</em>a rising star who could have had his pick of academic postings. Instead, he gave up a life in research to start a technology company he named <a href="http://www.otilumionics.com/">OTI Lumionics</a>.</p> <p>The failure rate of technology startups, by some estimates, is 90 per cent.</p> <p>Who would trade the life theyā€™d dreamed of for a chance to play Russian roulette with five chambers loaded? Someone whoā€™s counting on a lot more than just luck.</p> <p>Why the fuss about OLEDs? And what on earth is an OLED? The best answer to both questions is OTIā€™s first and only consumer product, <a href="https://aerelight.com/">the aerelight</a>. Itā€™s an aluminum table lamp&nbsp;ā€“&nbsp;sleek, angled, and a little retro (reminiscent of an older Canadian beauty, 1968ā€™s Contempra phone). The light comes from a 10-cm square wafer no thicker than two sheets of paper&nbsp;ā€“&nbsp;an OLED.</p> <p>Not only is the lamp beautiful, so is its light. OLEDs are cool to the touch but warm to the eye, dimmable, flexible and efficient. They donā€™t blaze from a single spot like LEDs; they diffuse evenly from every point on their surfaces, which can be arbitrarily large. After seeing the aerelight, other light sources&nbsp;ā€“&nbsp;whether incandescent, fluorescent, or LED&nbsp;ā€“&nbsp;immediately seem huge, hot and obsolete.</p> <p><img alt src="/sites/default/files/2015-02-25-Aerelight-%28Credit-Roberta-Baker%29.jpg" style="margin: 10px; width: 625px; height: 417px;"></p> <p>&nbsp;(<em>above photo by Roberta Baker</em>)</p> <p>Like a conventional light-emitting diode, an organic LED produces light when a voltage is placed across it. The difference is the material between the electrodes. Instead of a crystalline semiconductor, OLEDs use organic compounds&nbsp;ā€“&nbsp;plastics, in essence&nbsp;ā€“&nbsp;similar to the pigments used in colour Xerox machines.</p> <p>ā€œLEDs are grown from perfect single crystals,ā€ says Helander. ā€œThe probability of a defect increases exponentially with size, so itā€™s limited to a point source. Organic molecules donā€™t have any long-range order, so they donā€™t need a perfect single-crystal structure to work. Thatā€™s what allows you to distribute it across a large surface.ā€</p> <p>Lighting isnā€™t the only place the OLED shines. Itā€™s already made an appearance in smartphone displays and television screens, where its other advantages&nbsp;ā€“&nbsp;richer colours, deeper blacks and near-instantaneous response times&nbsp;ā€“&nbsp;make it the heir apparent to the liquid crystal display. But OTI is staying away from displays. Multinationals such as&nbsp;Samsung and LG have already spent billions to enter and fight over that market.</p> <p>Lighting, on the other hand, is still in its dark ages. Even the latest technology, the LED, comes packaged to resemble Thomas Edisonā€™s 1880 bulb. That paradigm is about to shift. Soon, a light wonā€™t be a product, but a feature of a surface&nbsp;ā€“&nbsp;any surface. Windows, walls and wallpaper, furniture, cars, and clothes: light will come from everywhere.</p> <p>If OTI succeeds, Toronto-born Helander will be the reason. Heā€™s a force of nature, intense, ambitious, and, at 29, astonishingly accomplished.</p> <p>As a kid, he wanted to be a scientist. Then he enrolled in the ³Ō¹Ļ±¬ĮĻā€™s engineering science program (ā€œbecause people said it was the hardestā€) and realized he wanted to be an engineer. While working on his PhD with <strong>Zheng-Hong Lu</strong>, professor and Canada Research Chair in Organic Optoelectronics in the department of materials science and&nbsp;engineering (ā€œThey had lots of shiny equipment, so that got me excitedā€), he realized he really wanted to be an entrepreneur.</p> <p>He reached that decision after stumbling on a major discovery. Helander and OTI cofounder <strong>Zhibin Wang</strong>&nbsp;were working with indium tin oxide (ITO),&nbsp;the industry-standard, transparent yet conductive coating used in every kind of flat-panel display,&nbsp;when they noticed something unexpected. Some of their samples were working far more efficiently&nbsp;ā€“&nbsp;carrying much more current&nbsp;ā€“&nbsp;than they should. They assumed their equipment was improperly calibrated, but soon ruled that out. The effect was real. Their ITO had been contaminated.</p> <p>It took months to find the culprit: chlorine from open bottles of cleaning fluid. ā€œBasically, breaking the safety rules,ā€ Helander quips. ā€œThe next step: how do we make use of it?ā€</p> <p>Helander, Wang and Professor Lu published their answer in <em>Science</em> in May of 2011: chlorinated ITO. A one-atom thick layer of chlorine dramatically increased the brightness of OLEDs while reducing their energy consumption by up to 50 per cent. It also drastically lowered their cost by reducing the number of organic layers needed to make a diode from as many as eight to just two or three.</p> <p>That news was greeted with considerable interest. ā€œBig companies started approaching us,ā€ Helander says. ā€œThey wanted to license or buy the technology. We thought, if theyā€™re willing to pay this much now, there must be much more value than theyā€™re letting on. Letā€™s try making a go of it ourselves.ā€</p> <p>So they created OTI Lumionics. The initials donā€™t stand for anything. Itā€™s just ITO backwards, a declaration that their approach would be 180 degrees from usual. ā€œLumionicsā€ is a fabricated word that sounds like light, a choice Helander somewhat regrets because nobody seems able to spell it.</p> <p>At first, Helander thought OTI would be nothing more than a stepping-stone to an academic career. ā€œWhen we started the company, we viewed it as another checkbox on the academic CV. Successfully commercialized tech: check.ā€</p> <p>But as the months rolled by, a desire to finish what theyā€™d started in the lab took root. Helander and Wang decided their future lay with OTI. (<a href="http://news.utoronto.ca/alumni-startup-oti-lumionics-awarded-57-million-produce-energy-efficient-lighting-solutions">Read&nbsp;about the most recent support for OTI Lumionics</a>.) Giving up academia for entrepreneurship wasnā€™t hard, Helander said. By the time heā€™d earned his PhD, his name was on over a hundred publications, more than most researchers produce in an entire career.</p> <p>ā€œWhen you get up to that number of publications itā€™s almost like a paper mill; itā€™s just a formula youā€™re repeating,ā€ he says. ā€œIt felt like we had learned the game and it wasnā€™t challenging anymore. We wanted new challenges.ā€</p> <p><img alt src="/sites/default/files/2015-02-25-OTI-team_%28Credit-Roberta-Baker%29-%282%29.jpg" style="margin: 10px; width: 625px; height: 417px;">(<em>Above photo of Helander (centre) with team by Roberta Baker</em>)</p> <p>Helander takes me into the back corner of OTIā€™s new offices in the University of Torontoā€™s venerable Banting Building on College Street. The room is dominated by a seven foot-tall vacuum-deposition chamber that looks like a giant robotic squid.</p> <p>ā€œThis is our rapid prototyping module for organic LEDs,ā€ he explains. ā€œIt allows us to make large, flexible panels in about an hour.ā€ He bends a six-inch square sheet of shiny blue-green plastic&nbsp;ā€“&nbsp;a freshly-made OLED&nbsp;ā€“&nbsp;into a half-cylinder. I want to ask for details, but Helander is already talking about his plans for the larger, still empty, room adjacent.</p> <p>ā€œThe pilot scale-up next door will be the same process, except itā€™ll be ten modules next to each other, so the production time goes down from an hour to minutes.ā€</p> <p>Before I can quiz him on that, heā€™s shifted gears again. ā€œThe step after that, starting next year, is building a full production plant, hopefully somewhere in southern Ontario.ā€ Helander speaks very fast, at the edge of comprehensibility, skipping syllables and sometimes entire words in a losing fight to keep up with his own thoughts. ā€œWeā€™ll be pulling together a whole syndicate of partners that are throwing in a whole bunch of support. Weā€™re hoping to get money from the province as well and raise another round of financing. Itā€™s a massive project.ā€</p> <p>Sounds ambitious. ā€œVery ambitious,ā€ he says. ā€œPeople tell us we have lack of focus. But to understand our customers, we have to have our hands in everything. At the same time, weā€™re a small company. For what weā€™re doing we should have ten times the personnel and twenty times the capital. Trying to do the impossible&nbsp;ā€“&nbsp;thatā€™s how you succeed.ā€</p> <p>Itā€™s clear Helanderā€™s ambition doesnā€™t stop at table lamps. In fact, it doesnā€™t even include table lamps&nbsp;ā€“&nbsp;or didnā€™t, until he and OTIā€™s senior product designer,<strong> Ray Kwa</strong>, built a few prototypes. Everyone who saw them had the same three questions: ā€œWhen can I buy it? When can I buy it? When can I buy it?ā€</p> <p><iframe allowfullscreen frameborder="0" height="360" src="https://www.youtube.com/embed/l_MTy-mS8cc" width="640"></iframe></p> <p>So OTIā€™s nine employees are making OLED panels and assembling lamps on College Street. At the same time, multibillion-dollar giants like Philips, LG and Konica Minolta are preparing to turn out OLED panels by the million. In a few months, OLED table lamps may be going for a fraction of the price&nbsp;ā€“&nbsp;$239 (USD)&nbsp;ā€“&nbsp;of an aerelight.</p> <p>Remarkably, Helander is unfazed by that prospect. ā€œThat would make us so happy,ā€ he says. ā€œIt would prove that weā€™re on the right track and the market is there.ā€</p> <p>Helanderā€™s plan is not to sell lamps but to service niches&nbsp;ā€“&nbsp;lots and lots of niches&nbsp;ā€“&nbsp;that are too small for the giants. ā€œThere are a lot of partners we work with who only want 10, 50, 100, units. A massive production line canā€™t do that effectively. Our vision is to enable hundreds of companies, delivering on-demand whatever people need, for applications in lighting, furniture, automotive, wearables, whatever you want.ā€</p> <p>Like any entrepreneur, Helander sounds more confident than he has any right to be. For the foreseeable future, OTI will live amongst threats: an untested market, ever-mutating technology, giants ready to grind him to paste, uncertain financial backing. To defend himself, Helander has little more than a small pool of talents, patents and ambitions.</p> <p>Of course, in his case, that might just be enough.</p> <p><em style="line-height: 18px; font-size: 12px;">Originally published in the 2015 issue of&nbsp;<a href="http://mse.utoronto.ca/alumni-industry/impact-magazine/03-2015/">Impact Magazine</a>.</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2015-02-25-OLED.jpg</div> </div> Wed, 25 Feb 2015 10:08:02 +0000 sgupta 6821 at Alumni startup OTI Lumionics awarded $5.7 million to produce energy-efficient lighting solutions /news/alumni-startup-oti-lumionics-awarded-57-million-produce-energy-efficient-lighting-solutions <span class="field field--name-title field--type-string field--label-hidden">Alumni startup OTI Lumionics awarded $5.7 million to produce energy-efficient lighting solutions</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2015-02-23T04:17:35-05:00" title="Monday, February 23, 2015 - 04:17" class="datetime">Mon, 02/23/2015 - 04:17</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"> Alumnus Michael Helander (centre) and his startup, OTI Lumionics, have received significant investment from the Canadian government to build a pilot production line capable of producing high-volumes of their organic LED lighting panels (photo by Roberta </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/luke-ng" hreflang="en">Luke Ng</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Luke Ng</div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/lighting" hreflang="en">Lighting</a></div> <div class="field__item"><a href="/news/tags/startup" hreflang="en">Startup</a></div> <div class="field__item"><a href="/news/tags/entrepreneurship" hreflang="en">Entrepreneurship</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/commercialization" hreflang="en">Commercialization</a></div> <div class="field__item"><a href="/news/tags/alumni" hreflang="en">Alumni</a></div> <div class="field__item"><a href="/news/tags/more-news" hreflang="en">More News</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Itā€™s about to get a whole lot brighter in Toronto thanks to a significant investment from the Canadian government in a University of Toronto engineering alumnusā€™ sustainable lighting company.</p> <p><a href="http://www.otilumionics.com/">OTI Lumionics</a>, a company co-founded by alumnus <strong>Michael Helander</strong>, has been awarded $5.7 million from Sustainable Development Technology Canada (SDTC).

A more efficient electricity-to-light conversion means perovskites could open new frontiers for energy-efficient LEDs.</p> <p>Parallel work in the Sargent Group focuses on improving nano-engineered solar-absorbing particles called colloidal quantum dots. ā€œPerovskites are great visible-light harvesters, and quantum dots are great for infrared,ā€ said&nbsp;Sargent.</p> <p>ā€œIn future, we will explore the opportunities for stacking together complementary absorbent materials,ā€ says Dr. Comin. ā€œThere are very promising prospects for combining perovskite work and quantum dot work for further boosting the efficiency.ā€</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2015-01-30-new-solar-crystals.jpg</div> </div> Fri, 30 Jan 2015 09:09:57 +0000 sgupta 6759 at World's first consumer-ready OLED lamp /news/worlds-first-consumer-ready-oled-lamp <span class="field field--name-title field--type-string field--label-hidden">World's first consumer-ready OLED lamp</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2014-10-15T04:10:34-04:00" title="Wednesday, October 15, 2014 - 04:10" class="datetime">Wed, 10/15/2014 - 04:10</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">aerelightā„¢ ā€“ the worldā€™s first consumer-ready OLED lamp, by ³Ō¹Ļ±¬ĮĻ Engineering alumni (photo by Roberta Baker)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/luke-ng" hreflang="en">Luke Ng</a></div> <div class="field__item"><a href="/news/authors-reporters/rj-taylor" hreflang="en">RJ Taylor</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Luke Ng &amp; RJ Taylor</div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/lighting" hreflang="en">Lighting</a></div> <div class="field__item"><a href="/news/tags/startup" hreflang="en">Startup</a></div> <div class="field__item"><a href="/news/tags/entrepreneurship" hreflang="en">Entrepreneurship</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/alumni" hreflang="en">Alumni</a></div> <div class="field__item"><a href="/news/tags/features" hreflang="en">Features</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">New product from alumni startup OTI Lumionics gives investors a glimpse of technology's potential </div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>If you visit the lighting section of your nearest hardware store, chances are youā€™ll be bombarded by the latest mega-efficient LED bulbs&nbsp;ā€“&nbsp;but to alumnus <strong>Michael Helander</strong>, that technology is old news.</p> <p>Helander and a team of former ³Ō¹Ļ±¬ĮĻ Engineering students recently released the worldā€™s first organic LED (or OLED) lamp, <a href="http://aerelight.com/">aerelight</a>ā„¢. The product harnesses the power of next-generation OLEDs to emit a warm light from a thin sheet of non-toxic, carbon-based materials.</p> <p>The lamp uses less energy than traditional sources, providing up to 1,000 lux of illumination&nbsp;<span style="font-size: 12px; line-height: 18px;">ā€“&nbsp;</span>double a typical office environment <span style="font-size: 12px; line-height: 18px;">ā€“</span>&nbsp;with only seven watts. It also features a dimming capability, wireless smartphone charging built into the base&nbsp;and, of course, an advanced OLED panel. (<a href="http://aerelight.com/">Read more about aerelight</a>.)</p> <p>OLEDs are a sophisticated type of light-emitting diodes that pass electricity through carbon-based dyes and pigments to power lights and displays. While weā€™ve seen this technology in certain high-end smartphones and premium flat-panel displays, this is the first consumer-ready indoor OLED lighting product ever made.</p> <p>ā€œWe started with a goal of building the aerelight desk lamp, first as a great product, and second as the first consumer-ready OLED lamp,ā€ said Helander, who co-founded <a href="http://www.otilumionics.com/">OTI Lumionics </a>to commercialize OLEDs in 2011. The startup manufactures the lamps in-house, and is scheduled to ship them to consumers in early 2015.</p> <p>ā€œWith traditional light sources, the bulb is a distinct separate entity from the fixture,ā€ said alumnus and OTI senior product designer <strong>Ray Kwa</strong>. ā€œWith aerelight, I wanted to create a seamless, continuous frame integrating the base, frame and light&nbsp;<span style="font-size: 12px; line-height: 18px;">ā€“&nbsp;</span>synonymous to the OLED light source itself which emits a diffused, fluid soft light.ā€</p> <p>Although the lampā€™s efficiency and sleek design are already <a href="http://business.financialpost.com/2014/09/29/let-there-be-oled-light-startup-sees-bright-future-in-organic-diodes/?__lsa=a83d-e1e0">making media headlines</a>, aerelight is actually part of a much greater strategy from OTI to make OLED technology cheaper and easier to manufacture.</p> <p>ā€œOLEDs have many unique characteristics that make [them] the ideal light source of the future, but potential growth has been stifled by the high manufacturing costs,ā€ said Helander.</p> <p>In 2011, then-PhD students Helander and <strong>Zhibin Wang</strong>, along with their supervisor Professor <strong>Zheng-Hong Lu</strong>, discovered a new method for cost-effective production of OLEDs. Publishing their work&nbsp;in <a href="http://www.sciencemag.org/content/332/6032/944.short">the leading journal, Science</a>, the trio used a single-atom-thick layer of chlorine that simplified the internal structure of OLED technology, while still achieving high brightness and efficiency.</p> <p>Shortly after the breakthrough, Helander and other ³Ō¹Ļ±¬ĮĻ Engineering alumni spun off the technology into OTI&nbsp;ā€“&nbsp;taking their ideas to the University's&nbsp;elite accelerator program in the <a href="http://www.creativedestructionlab.com/">Creative Destruction Lab</a>, based at the Rotman School of Management. Over eight months, they honed the necessary technical and business aspects of their company, while also meeting with Canadian business and entrepreneurship titans.</p> <p>The fledgling startup has already received significant interest from notable investors, including <strong>Lee Lau</strong>, ATI Technologies founder and a G7 fellow at ³Ō¹Ļ±¬ĮĻā€™s Creative Destruction Lab, and<strong> Roger Martin</strong>, former Rotman School of Management&nbsp;dean.</p> <p>ā€œThis is a great example of how new materials like OLEDs can be showcased in a product that represents a paradigm shift in indoor lighting and sustainable technologies,ā€ said Professor <strong>Jun Nogami</strong>, chair of ³Ō¹Ļ±¬ĮĻ's department of materials science and&nbsp;engineering.</p> <p>With their first product hitting desks soon, Helander and his team at OTI continue to make OLED technology more accessible than ever&nbsp;ā€“&nbsp;suggesting a bright future is in store for them as well.</p> <p>See aerelight for yourself:</p> <p><iframe allowfullscreen frameborder="0" height="315" src="//www.youtube.com/embed/1s0o1xkJo20?rel=0" width="560"></iframe></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2014-10-14-oti-lumionics.jpg</div> </div> Wed, 15 Oct 2014 08:10:34 +0000 sgupta 6569 at
