尽管单壁碳纳米管(SWNTs)作为聚合物光伏电池受体的研究目前取得了很大进展，但其在聚合物基质中的分散性很差，极大地阻碍了器件的整体性能。本文设计了一种新型的基于聚苯乙炔/单壁碳纳米管复合材料的体相异质结结构，以改善碳纳米管在复合材料中的分散性，基于它们的结构相似性和强相互作用。与基于聚(3-辛基噻吩基)/单壁碳纳米管复合层的普通控制装置相比，具有更好的分散性和更高的性能。
Although research on the use of single walled carbon nanotubes (SWNTs) as the acceptor in polymer photovoltaic cells is currently making great progress, their poor dispersion in a polymer matrix has greatly hindered the overall performance of the devices. Here a novel bulk heterojunction structure based on a poly(phenyleneethynylene)/SWNT composite was designed to improve the dispersion of SWNTs in the composite based on their structural similarity and strong interaction. Better dispersion and higher performance are achieved compared with a common control device based on a poly(3-octylthiophene)/SWNT composite layer.
