摘要
CdS and CdZnS films were successfully deposited on glass/indium tin oxide (ITO) substrates from an aqueous solution. The ratio of Cd/Zn has been identified by auger electron spectroscopy (AES). The deposited films have been confirmed by X-ray diffraction (XRD) and were found to crystallise in the hexagonal crystal system. The surface of the as deposited and annealed films was analysed using SEM. The improvement of crystallinity was confirmed by Raman spectroscopy and XRD. Photoelectrochemical studies were carried out by fabricating a PEC cell of configuration CdS/0.1M Na2SO4/ITO and the physical parameters were studied. Current-voltage measurements were performed. The results of the present investigation are discussed in detail.
