Research Abstract

We have investigated nano-crystalline germanium as a photovoltaic material. It usually shows no photo-sensitivity became of the strong p-type conduction due to negatively changed grain boundary defects. We could successfully suppress the p-type conduction, due to slight oxygen doping, and show that nano-crystalline germanium is a good candidate of narrow gap materials for photovoltaic devices.
