    Cuprous oxide (Cu2O) thin films have been prepared on ITO-coated glass substrates by electrodeposition technique from an aqueous solution containing copper acetate and sodium thiosulfate. Electrochemical kinetics of Cu2O films were investigated by cyclic voltammetry. The obtained films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV/Vis spectroscopy and electrical measurements. The X-ray diffraction results indicated that the synthesized Cu2O thin films had a good crystalline of deposited Cu2O thin films with a pure cubic structure. Morphological study showed a better compactness structure composed of pyramid shape. Optical band gap was found to be 2.103 eV. Electrical properties of Cu2O films showed a p-type semiconductor with low electrical resistivity of 100 Ω cm, carrier concentration of 3.62×1015 cm-3and mobility of 17.24 cm2 V-1s-1.
