Design and Manufactur of Solar Cell from ITO/ ZnO/ CdS/ CdTe by Thermal Vaporization Technique and Studying the Physical Properties

Abstract

In this research, (ITO, ZnO, CdS and CdTe) films had been prepared by thermal vaporization, where the films deposited on glass slides separately at (1350 °C) (XRD, AFM and UV) tests were done on the samples, and found that all films were multiple crystallization. And the ITO film was cubic structure at the favorite granular growth orientation (222). The results of X-Ray Diffraction showed that the film of Zinc Oxide was hexagonal structure at the favorite granular growth orientation (200). Also, the results showed that the CdS film was hexagonal structure at the favorite granular growth orientation (002). And the results showed that CdTe film was cubic structure at the favorite granular growth orientation (111). The results of Atomic Force Microscope (AFM).Were studied Also the absorption and transmittance spectra for all prepared films in wave length.
