Title: Substrate for solar battery and solar battery using said substrate
Inventor: KAKIGI HISASHI
IPC: H01L21/205
Filed: 1989-02-09
Abstract: PURPOSE:To increase the light absorbing quantity and to thereby improve the photoelectric conversion efficiency of a solar battery by forming the solar battery with both a solar battery substrate whose thin metal film surface is of texture structure and a photoelectric conversion layer. CONSTITUTION:A thin metal film is formed on a supporting body by means of a plasma CVD method using an organic metal compound made of elements such as aluminum, chromium, titanium or silver, and a source gas composed of such a diluted gas as hydrogen gas, helium and argon. The metal surface of a substrate to be thus obtained is provided with a texture structure having uniform irregularities of 500 to 10000Angstrom  in average depth. When a photoelectric conversion layer such as silicon, gallium-arsenide is arranged on this substrate, the surface of this photoelectric transfer layer will also have irregularities, thereby allowing its photoelectric conversion efficiency to be improved thanks to reduced surface reflectance with respect to an incident light beam. Accordingly, it is possible to obtain a solar battery having a high photoelectric conversion efficiency.
