利用共轭聚电解质 PFEOSO3Na 和氧化锌修饰氧化铟锡 (ITO) 电极，构建了高效的倒置聚合物太阳能电池 (PSC)。 PFEOSO3Na和氧化锌修饰的ITO电极具有高透明度、增加的电子迁移率、光滑的表面和较低的功函数。含有修饰ITO电极的PTB7:PC71BM倒置PSC实现了8.49%的高功率转换效率（PCE），超过了含有ZnO修饰ITO电极的对照器件（7.48%）。特别是PCE-10:PC71BM倒置聚合物太阳能电池实现了高达9.4%的高PCE。这些结果证明了一种提高倒置聚合物太阳能电池性能的有用方法。
Efficient inverted polymer solar cells (PSCs) were constructed by utilizing a conjugated polyelectrolyte PFEOSO3Na and zinc oxide to modify the indium tin oxide (ITO) electrode. The ITO electrode modified by PFEOSO3Na and zinc oxide possesses high transparency, increased electron mobility, smoothened surface, and lower work function. PTB7:PC71BM inverted PSCs containing the modified ITO electrode achieved a high power conversion efficiency (PCE) of 8.49%, exceeding that of the control device containing a ZnO modified ITO electrode (7.48%). Especially, PCE-10:PC71BM inverted polymer solar cells achieved a high PCE up to 9.4%. These results demonstrate a useful approach to improve the performance of inverted polymer solar cells.
