New PV cell generates electricity from UV and IR light

Last month at the meeting of the Japan Society of Applied Physics, a research group from the Kyoto Institute of Technology introduced a new photovoltaic cell that is capable of generating electricity not only from visible light, but from ultraviolet and infrared light as well. The research group, led by associate professor Saki Sonoda, hopes that this will lead to a more efficient PV cell that can be single-junction rather than the more conventional multi-junction.
