Abstract

We investigated physical properties of CuIn1-xGaxSe2 thin films grown by co-evaporator under various Cu environments. To study the effect of the Cu environments on absorber layer properties, thin films were fabricated under various reaction periods for different Cu flux on 2 stage process. We find the structural and electrical characteristics were affected by the reaction period on 2 stage process. The correlation between Cu flux variation on 2 stage process and solar cell performance was studied. The structural and electrical properties for various Cu flux were discussed.
