Chemical solution deposition methods namely photochemical and chemical bath depositions are used to deposit cadmium sulphide (CdS) thin films on insulating glass substrates. In photochemical deposition (PCD), the deposition occurs by light induced reactions in the chemical solution. A substrate is immersed in the deposition solution and irradiated with ultraviolet light. Then the compound is formed in the solution due to photochemical reactions and deposited in the irradiated region of the substrate. The reactions occur only in the irradiated region, and the deposition process can be easily controlled by turning on/off the light. While in chemical bath deposition (CBD), the deposition occurs by chemical reaction promoted by thermal energy. The films obtained by both methods are characterized by XRD, UV-Visible spectrophotometer, Photoluminescence and Raman measurements. A comparative analysis is presented.
