  Kyoto, Japan (SPX) Jan 20, 2017 Solar cells convert light into electricity. While the sun is one source of light, the burning of natural resources like oil and natural gas can also be harnessed. However, solar cells do not convert all light to power equally, which has inspired a joint industry-academia effort to develop a potentially game-changing solution. "Current solar cells are not good at converting visible light to electrical power. The best efficiency is only around 20%," explains Kyoto University's Takashi Asano, w ... read more |
