In this paper, we prepare thin films of CdS using the method of spray pyrolysis with thicknesses (150,200,250) nm. The optical, electrical and structural properties have been investigated for those films ready on glass substrates. Cadmium sulfide membrane has a polycrystalline structure of the hexagonal type. An increase in thickness did not affect the crystalline nature of the material as the material remained polycrystalline. Optical properties included the calculation of energy band gaps of the allowed direct electronic transitions. The energy band gap for CdS in the range (2.2-2.7)eV . The calculations also included some optical constants, such as transmittance also absorption coefficient. The increase in thickness led to an increase in the absorbance and absorption coefficient as well a decrease in the transmittance. The electrical properties include D. C. electric conductivity Hall effect. It was showing that the type of CdS films were (p-type).
