Abstract

A low cost chemical bath deposition technique has been used for the preparation of Copper aluminum diselenide (CuAlSe2) compound thin films onto commercial microscope glass substrates at variation of deposition temperature. The effects of deposition temperature (above room temperature (27°C)) towards the optical properties of the films were investigated. The optical properties were investigated by Jenway software 6405 UV-Vis spectrophotometer. The optical band gap energy of the films above room temperature ranges from 2.00 – 2.14 eV depending on the deposition temperature.
