Lin-led research with antireflective coatings solves two solar energy problems

A research team led by Shawn-Yu Lin, professor of physics at Rensselaer Polytechnic Institute and chair of the conference on Photonic and Phononic Crystal Materials and Devices at SPIE Photonics West, has discovered and demonstrated a new method for overcoming two major hurdles facing solar energy, moving the technology closer to enabling high-efficiency, cost-effective solar power, Rensselaer has announced.

Lin is an SPIE member, and has published more than 30 papers with SPIE, and has two scheduled for Photonics West in January.

The research team has developed a new antireflective coating that boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle. A press release issued by Rensselaer provides more details from a paper on the project published this week.

Among Lin's co-authors on the paper from Rensselaer are SPIE Fellow and Photonics West OPTO Symposium Chair E. Fred Schubert, Wellfleet Senior Constellation Professor of Future Chips; research assistant professor Jong Kyu Kim, author of several papers for SPIE including two scheduled for Photonics West; and electrical engineering graduate student Frank Mont, also an SPIE author.

Lin and Yong-Song Kim, also of Rensselaer, published a paper in the SPIE Newsroom in July on use of a photonic band-pass filter in developing an efficient, cool incandescent light bulb.
