AB  - We studied at the morphology, structural setup, and optical characteristics of thin 
cadmium (CdSe) films a thickness of 250 nm that were created by thermal evaporation 
over glass, The films exhibited a hexagonal shape were crystalline, and tended to form 
grains in the (111) crystallographic direction, according to the X-ray diffraction 
examinations. These characteristics were established using the investigation's findings. 
Through the use of thin films of CdSe doped with Ag at a concentration of 1.5%, the 
crystal structure orientations for pure CdSe (25.32, 41.84) and CdSe:Ag (25.39, 41.01) that 
were both pure as well as those that were doped with silver were both determined. The 
band gap of the optical spectrum decreased by 1.93–1.81 eV (300–700 nm). This reduced 
the rate of absorption measuring the current-voltage properties of heterojunctions made 
from a range of clean and doped materials with an incident electrical power density of 
(100 mW/cm<sup>2</sup>). The films' hexagonal structure was revealed by the X-ray investigation, 
and grain development was driven by the (220,111) crystallographic direction.
