PFN-溴

PFN-Br是可溶液加工的共轭聚电解质材料，可用作高性能有机光伏电池(OPV)和有机发光二极管(OLED)的界面层，提高其界面性能。
采用PFN-Br界面层的有机太阳能电池在短路电流密度、开路电压、填充因子参数的性能上都有增强，倒置OPV的效率提高。这是因为PFN-Br使ZnO电子提取层和活性层之间接触更易，电子提取层和活性层之间的界面结合性更好，并通过抑制双分子复合增强电荷传输。
最近报道的能量转换效率达17.3%的有机太阳能电池也采用了PFN-Br材料，将其旋涂在ZnO上以提高界面性能。

PFN-Br is a solution processible, conjugated polymer electrolyte used as interficial layer in high performance organic photovoltaic cells (OPV) and organic light emitting diodes (OLED) to improve the interfacial properties.
OPV devices with PFN-Br interfacial layer showed overall enhanced short-circuit current density, open-circuit voltage, fill factor and corresponding high efficiency in the inverted OPVs.This was attributed to the good contact between ZnO electron extraction layer and the active layer, good interface adhesion between the electron extraction layer and active layer, and enhanced charge transport via suppressed bimolecular recombination.
Recent report of OPV with a record energy conversion efficiency of 17.3% also utilized PFN-Br, spin-coated on top of ZnO to improve the interfacial properties.
