Abstract

In this paper we describe our research efforts directed towards the understanding of the CdS/CuInGaSe2junctions and, specifically, the interaction of the chemical bath with the CuInGaSe2 (CIGS). We find that Cd and S diffuse into the absorber during the CdS growth. Heating the absorbers in Cd partial baths resuled in a significant improvement in the ZnO/CIGS device properties. Photoluminescence measurements indicate that the effect of Cd is very similar to that of CBD CdS.
