本文讨论了中间带太阳能电池（IBSC）概念在提高薄膜黄铜矿太阳能电池效率方面的潜力。结果表明，CuGaS2基太阳能电池的辐射极限效率最高，达到46.7%。本文还描述了一种识别过渡元素的简单方法，该过渡元素在加入CuGaS2时可能引入中间带。IBSC概念也适用于薄膜太阳能电池不在聚光下工作以及存在不可忽略的非辐射复合贡献的假设。(c) 2008年美国物理研究所。
This paper discusses the potential of the intermediate band solar cell (IBSC) concept to improve the efficiency of thin-film chalcopyrite solar cells. The results show that solar cells based on CuGaS2, with a radiative limiting efficiency of 46.7%, exhibit the highest potential. A simple method for the identification of transition elements that when incorporated in CuGaS2 could possibly introduce an intermediate band is also described. The IBSC concept is also applied under the assumptions that thin-film solar cells are not to be operated under concentrated light and that a non-negligible contribution of nonradiative recombination exists.
