Electron beam evaporated cadmium sulphide thin films for solar cell applications
Cadmium sulphide (CdS) thin films were deposited by electron beam evaporation at different substrate temperatures. The structural characteristics were studied by the x-ray diffraction pattern. The CdS films are polycrystalline, exhibiting a preferred orientation along the (002) plane. Atomic force microscopy reveals that the root mean square roughness of the films increases as the substrate temperature increases. The optical band gap values of CdS films increase slightly with the increasing substrate temperature, in the range of 2.42–2.48 eV. The electrical characteristics of CdS/p-Si heterojunctions were investigated in dark condition and under the illumination intensity of 100 mW/cm2. Excellent rectifying and photovoltaic properties were observed.
