中文摘要：

有机太阳电池由于质轻、价廉、柔性，受到人们的广泛关注．单个有机材料只能吸收部分太阳光，叠层结构的太阳电池将不同吸收带隙的有机材料通过中间层连接起来，既能充分吸收太阳光，又能提高太阳电池的开路电压或短路电流．本文综述了近年来有机共混结构叠层太阳电池的研究进展，介绍了各种叠层有机太阳电池的结构、原理及性能，阐述了国内外有机叠层太阳电池研究的现状及存在问题，为高性能有机太阳电池的研究提供有价值的参考．

英文摘要：

Organic solar cells have received extensive attention due to their light weight, low cost, flexible. Because a single organic material absorbs only part of the sun light, laminated structure of solar cell, consisting of different absorption band gaps of organic material through the middle connecting layer, can both cover a larger part of the solar flux, and improve the circuit voltage or short circuit current of the solar cells. In this paper, the recent progress of the blend laminated structure polymer solar cells is summarized. Structures, principles and performances of a variety of laminated organic solar cells are introduced. The present status of research and existing problems of the blend laminated structure polymer solar cells are described, which provides valuable referesce for the study of high-performance organic solar cells.
