摘　　要：随着全球能源需求量的逐年增加,对可再生能源的有效利用成为解决日益严重的能源危机的主要手段,太阳电池被认为是清洁可再生新能源的代表之一。基于富勒烯和噻吩聚合物的本体异质结太阳电池因其制备简单、成本低廉、重量轻及可制成柔性器件等优点,近年来受到广泛关注,成为目前太阳电池的重要发展方向。经过努力,该种太阳电池的光电转化性能得到了一定提高,最高能量转化效率已达到6.5%,但是与无机半导体硅和染料敏化太阳电池相比还有一定差距。本文从材料合成的角度,简要综述了近年来国内外在基于富勒烯和噻吩聚合物的本体异质结太阳电池方面所取得的最新研究进展,并对下一步需要研究的热点问题作了展望。Organic and polymer photovohaic cells are becoming an extremely active research area to meet the urgent need for clean and renewable energy managements due to their potential applications as flexible, low cost and solution processable energy sources. The photophysics of such photoactive devices is based on the photo-induced charge transfer from donor-type semiconducting conjugated polymers to acceptor-type conjugated polymers or acceptor molecules such as buckminsterfullerene or C60. At present, so-called bulk heterojunction structures based on blends of a polymeric donor of polythiophene and the soluble fullerene derivative [6,6 ]-phenyl C61 butyric acid methyl ester （PCBM） as an acceptor component represent the material system with the highest power conversion efficiency reported to date （approximately 6.5% ）, and the regioregular head-to-tail polythiophene derivatives are still the most promising polymeric donor materials for such photovohaic cells, as their efficient interchain π-stackings of the conjugated backbones allow for the optimum transport of positive charge carriers （holes） until now. The present review summarizes and analyzes the progress made about the bulk heterojunction solar cells based on fullerene and polythiophene at home and abroad in the past few years. Some issues to be addressed and hotspots to be further investigated are also presented and discussed.
