Sputtering deposited CuInSe 2 films are of potential important as absorber material in thin film solar cells as long as we c an optimize the sputtering time processes to enhance their photoelectr ical properties . The results show that long t ime sputter ing processes exceeding to 3.0h can produce the particle aggregation and clusters to enhance the conversion efficiency of CuInSe CuInSe2 solar cells. Long t ime sputter ing processes ( 2.5, 3.0 and 4 .0h ) are found to be vital for the transformation from the InxSe phase to In 2 Se 3 and InSe structures. In addition, t he optical absorbance result show that the optical absorbance of CIS film at 4.0 h i s high er than the other films in the wavelength region above 3 00 nm . Also, the l ong t ime sputter ing processes (3.0 and can cause a significant increase in the optical band gap close to the best absorbed band gap of sunlight Finally, the I V chara cteristic curves show that the photoelectric conversion efficienc y of CIS film batter ies increase from 1.14% to 5.56% and short circuit current density increase from 12.63 to 22.26mA/cm2 with the sputtering time increase from 1.0 to 4.0h ..
