可溶性聚噻吩和富勒烯(主要是 C60)及其衍生物是聚合物太阳能电池中被广泛使用的给体和受体材料,它们之间的相容性和富勒烯的聚集效应对于太阳能电池能量转换效率有很大影响.将富勒烯与聚噻吩通过共价键连接在一起可解决它们的共混膜中的相分离问题,有望提高器件效率,是未来有机和聚合物光伏材料研究的一个重要方向.本文按主链是聚噻吩或齐聚噻吩将这种连有富勒烯的材料分为两类,介绍了这些材料的合成方法、电化学性质及基于这些材料的太阳能电池器件近几年来的研究进展.

Soluble polythiophene (PT) derivatives and fullerenes (mainly C60) are the donor and acceptor materials respectively well-used in the photosensitive blend layer of the polymer solar cells. Aggregation of the fullerenes and phase separation of the donor and acceptor materials in the blend layer influence the power conversion efficiency (PCE) of the devices. Connecting the PT donor with the fullerene acceptor together by covalent bond could solve the phase separation problem, so that increase the PCE of the polymer solar cells, which should be an important future research direction in the polymer photovoltaic materials. This review introduces recent research progress in the synthesis, electrochemical and photovoltaic properties of polythiophenes and thiophene oligomers with side chains containing fullerene.
