Cadmium sulphide (CdS) is one of the most promising electron-transporting materials in CdTe-based solar cells. In the present study, we use chemical bath deposition (CBD) technique to synthesize cadmium sulphide (CdS). The in?uence of solution pH level on the structural properties of CdS ?lms 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.
