In this paper the authors describe research efforts directed towards the understanding of the CdS/CuInGaSe{sub 2} junctions and, specifically, the interaction of the chemical bath with the CuInGaSe{sub 2} (CIGS). They find that Cd and S diffuse into the absorber during the CdS growth. Heating the absorbers in Cd partial baths resulted in a significant improvement in the ZnO/CIGS device properties. Photoluminescence measurements indicate that the effect of Cd is very similar to that of chemical bath deposition (CBD) CdS.
