Abstract: ZnO nanostructured arrays were deposited on Cu ( In, Ga ) Se2 thin film solar cells by electrodeposition as anti-reflective layer .The characteristics including morphology , optical quality and reflectance were optimized by controlling the deposition potentials .The I-V results of the solar cells with electrodes show that the anti-reflective layer efficiently suppress the surface reflections and advance light absorptions utilizing the moth-eye effect formed by the subwavelength size of ZnO nanostructures , which realize the short-circuit current increased by 6 .2;, and the efficiency enhanced by 9 .9;.
