ABSTRACT = {We investigated at the optical properties, structural makeup, and morphology of 
thin films of cadmium telluride (CdTe) with a thickness of 150 nm produced by 
thermal evaporation over glass. The X-ray diffraction study showed that the films 
had a crystalline composition, a cubic structure, and a preference for grain 
formation along the (111) crystallographic direction. The outcomes of the inquiry 
were used to determine these traits. With the use of thin films of CdTe that were 
doped with Ag at a concentration of 0.5%, the crystallization orientations of pure 
CdTe (23.58, 39.02, and 46.22) and CdTe:Ag were both determined by X-ray 
diffraction. orientations (23.72, 39.21, 46.40) For samples that were pure and those 
that were doped with silver, the optical band gap shrank by (1.52-1.47) eV 
(400–1100)nm resulting in a drop in the absorption coefficient. An incident power 
density of (100 mW/cm2) was used to examine the I-V properties of 
heterojunctions created by light on a variety of clean and doped materials. In 
accordance with the X-ray diffraction analysis, the films had a cubic structure and 
dominated grain growth along the (111) crystallographic direction. },
