Abstract

The cathodic electrodeposition of cadmium telluride on conducting transparent indium tin oxide (ITO) coated glass plates from an acidic aqueous bath containing CdSO4 and TeO2 is described. The study of the thermodynamic aspect of electrodeposited CdTe has allowed us to predict the deposition potentials range. The influece of deposition potential and bath temperature on the structure and cristallinity were investigated. X-ray diffraction analysis showed that the films deposited at room temperature are not cristallized whereas those deposited at higher temperatures have a cubic structure. A decrease of the potential improves the cristalline quality. Photoelectrochemical characterization of the deposit in aqueous polysulfide as an electrolyte was used to determine the conduction type and the effect of deposition potential on the photocurrent.
