Abstract

Modification of a ZnO cathode by doping it with a hydroxyl-containing derivative - giving a ZnO-C60 cathode - provides a fullerene-derivative-rich surface and enhanced electron conduction. Inverted polymer solar cells with the ZnO-C60 cathode display markedly improved power conversion efficiency compared to those with a pristine ZnO cathode, especially when the active layer includes the low-bandgap polymer PTB7-Th.

摘要

通过掺杂含羟基衍生物来修饰 ZnO 阴极——得到 ZnO-C60 阴极——提供了富含富勒烯衍生物的表面并增强了电子传导。与具有原始 ZnO 阴极的倒置聚合物太阳能电池相比,具有 ZnO-C60 阴极的倒置聚合物太阳能电池显示出明显提高的功率转换效率,特别是当活性层包括低带隙聚合物 PTB7-Th 时。
