Abstract
The present invention relates to a process for producing CuInSeand CuInGa,Sethin films used as an absorption layer for a solar cell such that they have a structure near to chemical equivalence ratio. The present invention provides a process for producing a thin film for a solar cell, comprising forming an InSe thin film on a substrate by Metal Organic Chemical Vapor Deposition using a [Me2In-(μSeMe)]precursor; forming a CuSe thin film on the InSe thin film by Metal Organic Chemical Vapor Deposition using a (hfac)Cu(DMB) precursor, and forming a CuInSethin film on the CuSe thin film by Metal Organic Chemical Vapor Deposition using a [MeIn-(μSeMe)]precursor. Further, the process may further comprise forming a CuIn,Ga,Sethin film on the CuInSethin film by Metal Organic Chemical Vapor Deposition using a [Me2Ga-(μSeMe)]precursor.
