Abstract

We have fabricated CIGS thin film absorber layers by the evaporation of CIGS powders which were synthesized by solutions with different atomic ratio compositions. We found that the polycrystalline structural properties and optical properties of the deposited CIGS thin films were strongly dependent on the CIGS powder synthesis solution compositions. For three different solution compositions, Cu:In:Ga:Se= 4:3:1:8, 8:3:1:8, 12:3:1,8, the deposited thin film crystalline structures were varied form InSe crystalline structure to CIGS chalcopyrite structures. Our results showed that CIGS powder evaporation is potential for the one step fabrication process for CIGS thin film absorber layer deposition.
