By creating a new way for light and matter to interact, UC Irvine researchers have enabled the manufacturing of ultrathin silicon solar cells that could help speed the shift from fossil fuels to renewable energy. “Solar energy is key in this transition, yet the commercial solar cells we rely on are falling short,” said Eric Potma, a professor of chemistry (far right above, with Dmitry Fishman, adjunct professor of chemistry, center, and Ara Apkarian, Distinguished Professor emeritus of chemistry). “Silicon’s poor ability to absorb light means that these cells require thick layers – almost 200 micrometers of pure crystalline material – to effectively capture sunlight . . . The thin-film solar cells that are one step closer to reality due to our research are widely seen as the solution to these challenges.”
