CuInSe{sub 2} thin films were grown on glass substrates using the chemical spray pyrolysis technique. The CuInSe{sub 2} films were co-deposited from aqueous solutions containing CuCl{sub 2}, InCl{sub 3}, and SeO{sub 2} used as Cu, In and Se precursors respectively. EDC was used as a complexing agent and films were grown at the constant temperature of 270°C. The films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy dispersive analysis of X-rays (EDAX) and the results indicate that the films are single phase, p-type in conductivity and have the chalcopyrite structure. Optical study shows that the optical band gap value is 1.03 eV. From the XRD study it is clear that the average crystallite size of the films is in the range 50 to 70 nm.
