The Role Of Cadmium Oxide Within The Thin Films Of The Buffer Cds Aimed At Solar Cells Based Upon CIGS Films Fabrication

Abstract

High quality Cadmium Sulphide thin films were grown on directly heated substrates of commercial glass by means of Modified Chemical Bath Deposition. Structural and optical properties of the obtained films were achieved. The impact of heat treatment in air at 450°C for one hour reveals the apparition of nano films of Cadmium Oxide on the surface of these buffer layers, which decreases dramatically the optical performance of the annealed films of CdS.
