Preparation and Characterization of Chemical Bath Deposited CdS Thin Films for Solar Cells
Chemical bath deposition of CdS thin film for solar cells was investigated in this study.CdS thin films were prepared by chemical-bath deposition (CBD) from a bath containing cadmium acetate,ammonium chloride,ammonium hydroxide and thiourea in aqueous solution on the glass substrate at certain bath temperature.The characterization of samples was conducted by using different methods such as scanning electron microscopy (SEM),X-ray diffraction (XRD) and ultraviolet spectrophotometry (UV).The crystal quality of CdS thin films was improved after CdCl2 thermal annealing at 400℃.The results showed that chemical bath deposited CdS thin film was symmetrical and compact,but depositing rate was low.As a result,the best deposition conditions were summarized,such as the pH value was about 10.5,depositing time was 60 minutes.
