The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities. Doping with isovalent and larger-sized alkali ...

French scientists have studied the fabrication of silicon heterojunction cells with p-type wafers. With the adoption of gallium doping, the p-type products could come close to matching the performance ...

Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...
