Summary and outlook for Light, Energy and the Environment Congress

By Baohua Jia | Posted: 15 December 2014

As a researcher working in the photonics field, I found this Congress was extremely useful. I attended many solar energy related conferences before and I had been always struggling to understand the technique jargons in solar cell research. And I wouldn’t bother to record so many details on thin-film deposition, which are highly equipment dependent. This time I am very glad to find that the two communities, namely the solar cell and the photonics people started to talk the same language. To my mind, having the right language of communication can lead to the identification of the challenges, which has already pushed more than halfway through towards solving the problem.

Day Four: Nobel Laureate addressed Solar Energy in a Sustainable World

By Baohua Jia | Posted: 15 December 2014

In the first plenary session of the Congress today, the Nobel Laureate, Professor Steven Chu presented a talk on “Solar Energy in a Sustainable World”. He reminded the audience that almost all energy formats including fossil fuel, wind, fission, geothermal energy are ultimately derived from the sun. He also raised the very important but often neglected point that from system point of view the overall up-take of the solar energy depends not only on the efficiency and cost of the solar cells, as we normally concerned in the academic world. Rather, the reliability of the energy source plays a significant role. If the energy fluctuation is larger than 5%, it is unlikely for the suppliers to choose this source. This is why the current research on the highly efficient batteries is crucial for pushing solar energy as a stable main stream energy source.

Day Three: Panel Discussion-the Future of Energy with Light

By Baohua Jia | Posted: 15 December 2014

Day three of the Congress started with a very fascinating talk given by Toshihiko Iwasaki, Konica Minolta, Japan. He reviewed comprehensively the status of OLED lighting activities at KONICA MINOLTA as well as the advancements in OLED materials and systems. He also presented the latest development on all-phosphorescent white OLED device, progress on solution-processed OLED technologies and the prospects for future development.

Things you can’t miss on Day Two

By Baohua Jia | Posted: 3 December 2014

On the second day of the Congress, there are a few interesting talks that I will recommend. The first series of invited talks are about advances in highly efficient organic light emitting devices (OLED) that will be in the morning session. Using different nanostructure designs the lightening efficiency can be improved significantly. The second series of invited talks are about the surface textures and light management in solar cells. New ideas/concepts on nanostructure design and fabrication will be presented on how to improve the solar cell performance using the photonic strategies. This session will be from 2-4pm.

Day One of the Light, Energy and Environment Congress

By Baohua Jia | Posted: 2 December 2014

Day one was a busy and exciting day. There were so many things happening. Four parallel sessions were up running. Many interesting talks were given from government officials, vice chancellor of Australian National University, famous professors and early career researchers about the energy issues and using the advanced photonics technology in solving the energy and environment challenges. I met lots of old friends, who previously worked in other sectors of photonics but now moved to the renewable energy sector. I also met lots of new friends and found a couple of researchers working in the very interesting complementary areas that I was planning to move to. After a few chats during the Congress reception a number of collaboration projects were already being planned.

Starting Now: OSA Light, Energy and the Environment Congress

By Baohua Jia | Posted: 1 December 2014

The Congress is starting today! With four featured topical meetings, the Congress is going to provide you the most comprehensive and advanced frontiers of optical technologies for energy production, transport, and usage. It’s going to be a feast for photonics lovers, who are longing to see the great impact of optics and photonics in the energy sector. As a researcher in the photonics field, my excitement also lies in the great potential to find niche opportunities to collaborate with people from different fields to accomplish this great energy challenge. The Congress plays the first horn of the International Year of Light.
