Title: CdCl2 Treatment, S Diffusion, and Recombination in Polycrystalline CdTe

Abstract

Time-resolved photoluminescence measurements on glass/SnO{sub 2}/CdTe and glass/SnO{sub 2}/CdTe/CdS structures indicate that the CdCl{sub 2} process, without any S present, significantly reduces recombination. However, S diffusion is required for lifetimes comparable to those observed in high-efficiency solar cells. Low-temperature photoluminescence, cathodoluminescence, and scanning electron images indicate how defect chemistry, grain-boundary passivation, and morphology are affected by S diffusion and the CdCl{sub 2} treatment.
