Self-cooling solar cells boost power, last longer
Technologies PV - Matériaux
Jeudi, 31 Juillet 2014 16:22

Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells -- keeping them cool, even in the blistering heat of the noonday sun. By adding a specially patterned layer of silica glass to the surface of ordinary solar cells, a team of researchers has found a way to let solar cells cool themselves by shepherding away unwanted thermal radiation.
