Abstract
The thin films of Cadmium sulphide (CdS) materials were prepared on glass substrates by thermal vacuum evaporation technique. X-ray diffraction (XRD) pattern of the deposited films showed cubic structure with a preferred orientation along the (111) plane. The grain size and lattice constants were measured from XRD data. The optical properties such as transmittance, reflectance, absorption co-efficient and band gap were investigated. The band gap was found from 2.59eV to 2.67eV for thickness varied from 100 nm to 50 nm. The thickness of the film was measured by insitu thickness monitor. The compositional parameter showed that the presence of compound CdS of the films. The deposition condition and the deposition technique showed its suitability for photovoltaic application.
