Influence of deposition time in CdTe thin film properties grown by Close-Spaced Sublimation (CSS) for photovoltaic application

Cadmium Telluride (CdTe) thin films were grown on borosilicate glass substrates by close-spaced sublimation (CSS) at a pressure of 1.5�2 Torr in Ar ambient. CdTe thin films were sublimed at a source temperature of 625 �C and substrate temperature of 595 �C. In this study, the impact of various depos...
