【Abstract】 CdS thin films were obtained by electrodeposition.The structure and surface morphology of the films was studied by X-ray diffraction(XRD) and scanning electron microscope(SEM) method respectively.The influence of different applied potential and temperature on the stoichiometry of the CdS films was investigated.The optimal applied potential was about 2.5-3.0V.The solar cells with the structure of ITO/n-CdS/p-SnS/Ag have been made.The photovoltaic properties of a open-circuit voltage of 0.2V,a short-circuit current of 13.2mA/cm~2,a filling factor of 0.31,and a conversion efficiency of(0.81%) were obtained under the illumination of 100mW/cm~2.更多还原
