Abstract
Time-resolved photoluminescence measurements on glassSn O2 CdTe and glassSn O2 CdTeCdS structures indicate that the Cd Cl2 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 Cd Cl2 treatment.
