摘要

近年来为获得有机聚合物太阳能电池更高的能量转换效率

越来越多的活性层材料被设计合成出来

尤其是给体材料。其中

基于给体单元苯并二噻吩(BDT)的D-A型窄带隙共轭聚合物更是多次刷新了有机聚合物太阳能电池效率的最高记录

目前达10.6%。本文探讨了基于苯并二噻吩的D-A型窄带隙共轭聚合物材料结构及其应用在太阳能电池中的性能参数关系

从提高开路电压、短路电流和填充因子三个方面总结出了提高基于BDT共轭聚合物太阳能电池能量转换效率的方法。

Abstract

To pursue high power conversion efficiency (PCE) of polymer solar cells(PSCs)

more and more new active layer materials
