Abstract

PURPOSE:To improve conversion efficiency of a Si thin film solar cell and reduce the necessary material by composing a semiconductor layer for photoelectric conversion of fine crystal Si whose average particle diameter is not more than 100Angstrom . CONSTITUTION:A semiconductor layer for photoelectric conversion is composed of fine crystal Si whose average particle diameter is not more than 100Angstrom . Such fine crystal Si can be made grow on a substrate by decomposing mixed gas of SiH4 and H2 in plasma generated by DC or AC field. It is necessary to have the applied DC or AC power higher in such case than in the case of forming an amorphous Si film. The absorption coefficient for the light depends upon the size of the crystal particle diameter and it is important that the average particle diameter is not more than 100Angstrom . The light absorption coefficient for the light of 550nm which is near the peak of the radiation energy of the solar spectrum is 8X10<4>cm<-1> in the case of the amorphous Si and 4X 10<5>cm<-1> in the case of the fine crystal Si whose average particle diameter is not more than 100Angstrom and the decline is small, so that the necessary thickness is good enough to be about 2mum.
