UNIVERSITY PARK, Pa., Sept. 14 -- Pennsylvania State University issued the following news release:
UNIVERSITY PARK, Pa. - Remember the solar calculator from middle school math class that had a small solar cell at the top? The idea behind that technology is not a relic of the past, but the subject of continuous innovation. Today's indoor solar cells, known as photovoltaics, use new semiconductor materials, such as metal halide perovskite, to convert ambient light into electricity to power small electronic devices without needing batteries or a power outlet. Now, a team led by materials science researchers at Penn State has improved perovskite's ambient light-absorbing ability and its capacity to remain stable over time even at high light in...
