Photovoltaic device

Abstract

Abstract PURPOSE:To enhance optoelectronic conversion efficiency, in a photovoltaic device, having a three-layer structure, in which an amorphous film is held between a transparent electrode and a metal electrode, by providing light reflecting particles, which elongate a light path in an amorphous film, on the light path of incident light. CONSTITUTION:Diamond particles 5 are provided on a flat substrate 1 by a plasma CVD method. Part of incident sunlight 6 is absorbed into an amorphous film 2 and transduced into electric power. The sunlight 6, which is reflected by the diamond particle 5, again advances in the amorphous film 2, and the part of the light is absorbed in the amorphous film 2 and transduced into electric power. The generated electric power is taken out of an amorphous solar cell through the conductive substrate 1 and a grid electrode 4.
