| 摘 要： | 利用电化学沉积法在铜铟镓硒薄膜太阳能电池表面沉积一层ZnO纳米结构阵列减反射层.通过对沉积电位的操控,实现了对该纳米结构减反射层形貌、光学质量、反射率等特性的优化.在电池表面蒸镀电极后测试电池的电流电压曲线可知,相比于没有减反层的电池,沉积了纳米结构减反射层的电池利用氧化锌纳米结构的亚波长尺寸形成的蛾眼效应有效降低了表面光反射,增加光吸收,从而实现短路电流增加6.2;,电池效率提高了9.9;.

| 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%. |

| Keywords: | ZnO nanorod anti-reflective coating electrodeposition short-circuit current photoelectric conversion efficiency |
