ABSTRACT

Thin films of CdSe were deposited by electrodeposition technique on substrate of fluorine tin–oxide (FTO) coated glass using aqueous bath solution containing 0.02 M CdSO4 (10 mL) + 0.2 M EDTA (1 mL) + 0.010 M SeO2 (10 mL) at 750C temperature. The preparative parameters were optimized to get good quality CdSe thin films. These films were characterized by X-ray diffraction (XRD), optical absorption and photoelectrochemical (PEC) techniques. The XRD analysis of the deposited film showed presence of polycrystalline in nature with hexagonal structure. The surface morphology studies by scanning electron microscope ( SEM ) shows that the deposited film are well adherent and grains are uniformly distributed over the surface of substrate.
