Temperature influence study on copper selenide films

Abstract

Copper selenide was prepared by film is successfully deposited on a Fluorine-doped Tin Oxide (FTO) substrate by a brush plating technique. The film was uniform, had good adherence to the substrate and was annealed at 300• C and 500• C. As the annealing temperature increased, the orientation of the crystallites is more randomized than in the as-prepared film. The structural and optical properties of the film were investigated by XRD, SEM, EDAX, UV-Visible and PL. The XRD pattern indicated that this film was crystalline in the structure.

Structural, optical and morphological study of tungsten selenide thin films

“…Optical characterization has been performed and band gap values were obtained for the films which revealed that the films possessed very good optical properties necessary for the materials used in solar cells [9].…”
