Abstract

Deposition technique of a-SiGe:H and its application to a stacked solar sell were investigated. Properties of a-SiGe:H were improved by a glow discharge method with a negatively biased substrate, and a mercury sensitized photo CVD under lower pressure. An a-SiGe:H single junction solar cell was improved by slight boron doping to an i layer and insertion of a buffer layer into a p/i interface. A conversion efficiency of more than 10 % was obtained by a triple stacked solar cell on a alass substrate.
