SOLAR - Super-Efficient Solar Cells Possible Through Use Of Exotic Form Of Silicon, Generating More Than One Electron-Hole Pair Per Photon

By utilizing an exotic form of silicon, silicon BC8, it is very likely possible to significantly raise the efficiency of solar cells, according to new research headed by the University of California, Davis.Solar cells currently in use generate one electron-hole pair for every photon that hits them, and are capable of a theoretical maximum efficiency of 'only' 33%. But by utilizing nano-particles of an exotic form of silicon known as silicon BC ...
