Cubic zinc sulfide (c-ZnS) thin films have been prepared using dipcoating technique. X-ray diffraction pattern revealed cubic phase with the preferred (111) plane in ZnS films. Scanning electron microscope (SEM) analysis showed the granular shaped type of surface texture. The energy dispersive X-ray method indicated an excess of zinc. UV-Visible spectroscopy is used to measure the transmittance of thin films which is found to be superior to 80 %. These experimental results showed that the as-grown ZnS nanoparticles were of high purity.

Cadmium sulfide (CdS) is one of the most promising electrontransporting materials in CdTe-based solar cells. In the present study, we use chemical bath deposition (CBD) technique to synthesize cadmium sulphide (CdS). The influence of solution pH level on the structural properties of CdS films was studied using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). X-ray diffraction (XRD) analysis revealed that the as-grown CdS thin films were polycrystalline in nature, consisting of hexagonal wurtzite phase. SEM images showed grains uniformly distributed over the surface of the substrates, and EDS results demonstrated that the composition analysis of Cd:S ratio is close to 1:1. These CdS layers are expected to enhance the current, resulting in best photovoltaic performance for CdTe-based solat cells.
