Inorganic binary and ternary compounds are considered as key materials in applications related to solar energy conversions. In this paper, we report on the chemical synthesis of ternary cadmium cobalt selenide thin film and studies on some of its properties. A cadmium cobalt selenide film of 0.92 mu m thickness on glass substrate shows a uniform spherical morphology. An XRD analysis confirms the presence of individual cubic cadmium selenide and cobalt selenide phases formulated in a homogeneous, grainy morphology. The optical absorbance study gave a single absorption edge at similar to 680 nm corresponding to optical band gap of 1.84 eV, while emission spectra exhibited a strong emission band at similar to 675 nm at room temperature corresponding to a fundamental band gap. A photo-electrochemical cell constructed reports a conversion efficiency of 0.742 % with a fill factor of 37.70 %.
