Dual essential parameters must be considered in manufacturing of such materials. They are optical gap corresponding to solar range and affordability of fabrication price. Between the materials of abundant attention are crystalline metal chalcogenides. Numerous semiconducting photoelectrodes were comprehensively considered for electrochemical generation of current by using radiation in terms of continuous and effective trap as well as exchange of solar power. This dissertation illustrate the synthesis and characterization of polycrystalline cadmium selenide/trivalent ion like aluminum doped cadmium selenide/ monovalent ion like copper doped cadmium selenide thin films. Solar cells maintain great hopes to be used an environmental friendly and economically feasible renewable power sources. For this purpose semiconductor materials are being investigated. In the present investigation, deposition of cadmium selenide/aluminum and copper doped cadmium selenide samples by dip method applying amorphous as well as metallic templates. Aluminum trichloride, cadmium sulfate, ammonia,trichloroacetic acid, aluminum trichloride, sodium selenosulphate and copper chloride were utilized to deposit the samples. Diverse depositary considerations were outlined to acquired excellent samples. The materials have been characterized via XRD technique, SEM method, optical absorption measurement and electrical characteristics. The sample undergoes photoelectrochemical and thermoelectrical determination. Cadmium selenide films show dark red in color. For aluminum and copper doped samples different shades and dark brown color was obtained correspondingly. The extreme thickness of cadmium selenide became observed 0.54μm, aluminum doped sample indicates 0.74 μm as well as 0.70μm for copper doped samples. Each sample indicates hexagonal structure. Cadmium selenide and aluminum doped sample represents a strong peak o
