摘要: CuInGaSe2薄膜太阳能电池因具有稳定、高效、低成本和环保等特点而受到国内外科学家的重视.采用Mo/钠钙玻璃衬底为研究电极,饱和甘汞电极(SCE)为参比电极,大面积的铂网电极为辅助电极的三电极体系,在钼/钠钙玻璃衬底上利用电沉积技术制备出太阳能电池用的CuInGaSe2薄膜.分析了不同热处理温度对电沉积制备的CuInGaSe2薄膜的影响,结果表明:当热处理温度为450℃时,所制备的CuInGaSe2薄膜的化学组成接近理想的化学计量比,薄膜具有黄铜矿结构,颗粒均匀和致密性较好.

Abstract: CuInGaSe2 thin films solar cells have been drawn much attention due to their potential for the fabrication of low-cost, high-efficiency, and high stability. CuInGaSe2 thin films were fabricated by electrodeposition, where the reference electrode was a saturated calomel electrode (SCE), the counter electrode was Pt gauze and the working electrode was a Mo/soda lime glass substrate. The influence of different heat-treatment temperature on the CuInGaSe2 thin films was analyzed. The results indicate CuInGaSe2 thin films by electrodeposition is near to the ideal stoichiometry and have chalcopyrite structure and uniform grain when the temperature is 450℃.

Key words: CuInGaSe2, thin films, heat-treatment, solar cells, electrodeposition
