This research investigates the consistency of chemical bath deposition (CBD) for CdTe thin films. Films were deposited using tellurium dioxide and cadmium acetate in a non-aqueous medium at 160°C. The impact of subsequent annealing on the optical, structural, and surface properties of these films was examined. XRD, FTIR, UV-Vis, SEM, and photoluminescence techniques were used to characterize the films. EDS analysis revealed a Cd:Te ratio of 1.27 before annealing, which improved to 1.06 (closer to the ideal 1:1 ratio) after annealing. The average crystallite size of annealed CdTe film was around 25nm. Photoluminescence peaks were observed at 566 nm and 615 nm.
