聚合物太阳能电池（PSC）由夹在PEDOT：PSS涂覆的ITO正电极和低功函数金属负电极之间的共轭聚合物供体和可溶性富勒烯衍生物受体的共混物膜组成。共轭聚合物给体和富勒烯衍生物受体是制备高性能PSC的关键光伏材料。在受体方面，虽然目前主要使用[6，6]-苯基-C-61-丁酸甲酯（PC60 BM）及其相应的C-70衍生物PC 70 BM作为PSC的受体，但近年来报道了几种具有更高LUMO能级和更好溶解性的新型富勒烯衍生物，以进一步提高PSC的功率转换效率。本文综述了近年来富勒烯衍生物受体的研究进展，包括各种类PC60 BM的C-60衍生物、PC60 BM双加成物、PC 70 BM双加成物、茚-C-60双加成物和茚-C-70双加成物、三金属氮化物内嵌富勒烯以及其它多侧链的C-60衍生物。考虑到两种富勒烯受体的重要性，本文还介绍了PC60 BM和PC 70 BM的合成和理化性质。
Polymer solar cells (PSCs) are composed of a blend film of a conjugated polymer donor and a soluble fullerene derivative acceptor sandwiched between a PEDOT:PSS coated ITO positive electrode and a low work function metal negative electrode. The conjugated polymer donor and the fullerene derivative acceptor are the key photovoltaic materials for high performance PSCs. For the acceptors, although [6,6]-phenyl-C-61-butyric acid methyl ester (PC60BM) and its corresponding C-70 derivative PC70BM are dominantly used as the acceptors in PSC at present, several series of new fullerene derivatives with higher-lying LUMO energy level and better solubility were reported in recent years for further improving the power conversion efficiency of the PSCs. In this perspective paper, we reviewed the recent research progress on the new fullerene derivative acceptors, including various PC60BM-like C-60 derivatives, PC60BM bisadduct, PC70BM bisadduct, indene-C-60 bisadduct and indene-C-70 bisadduct, trimetallic nitride endohedral fullerenes and other C-60 derivatives with multi side chains. The synthesis and physicochemical properties of PC60BM and PC70BM were also introduced considering the importance of the two fullerene acceptors.
