Novel poly[(9,9‐bis((6′‐(N,N,N‐trimethylammonium)hexyl)‐2,7‐fluorene)‐alt‐(9,9‐bis(2‐(2‐(2‐methoxyethoxy)ethoxy)ethyl)‐9‐fluorene)) dibromide (WPF‐6‐oxy‐F) and poly[(9,9‐bis((6′‐(N,N,N‐trimethylammonium)hexyl)‐2,7‐fluorene)‐alt‐(9,9‐bis(2‐(2‐methoxyethoxy)ethyl)‐fluorene)] dibromide (WPF‐oxy‐F) compounds are developed and the use of these water‐soluble polymers as an interfacial layer for low‐cost
新型聚[(9,9-bis((6'-(N,N,N-三甲基铵)己基)-2,7-芴)-alt-(9,9-bis(2-(2-(2-甲氧基乙氧基)乙氧基)乙基)-9-芴))二溴化物(WPF-6-氧基-F)和聚[(9,9-双((6'-(N,N,N-三甲基铵)己基)-2,开发了7-芴)-alt-(9,9-双(2-(2-甲氧基乙氧基)乙基)-芴)]二溴化物(WPF-oxy-F)化合物,并将这些水溶性聚合物用作界面低成本聚(3-己基噻吩):苯基C 61层研究了丁酸甲酯(P3HT:PCBM)有机太阳能电池(OSC)。通过旋涂水溶性聚芴简单地将WPF-oxy-F或WPF-6-oxy-F作为界面偶极层插入有源层和阴极之间时,开路电压(V oc),填充系数(FF)和具有高功函数金属阴极(例如Al,Ag,Au和Cu)的光伏电池的功率转换效率(PCE)显着提高。例如,当WPF-6-oxy-F与Al,Ag,Au或Cu一起使用时,无论金属阴极的功函如何,V
