说明

PFN-Br 是一种可溶液加工的共轭聚合物电解质,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,以改善界面性能。

具有 PFN-Br 界面层的 OPV 器件在倒置 OPV 中表现出整体增强的短路电流密度、开路电压、填充因子和相应的高效率。 这归因于 ZnO 电子提取层和有源层之间的良好接触,电子提取层和有源层之间良好的界面粘附,以及通过抑制双分子复合增强电荷传输。

应用

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.

Tandem Cell Device performance:
ITO/ZnO/PFN-Br/PBDB-T:F-M/M-PEDOT/ZnO/PTB7- Th:O6T-4F:PC71BM/MoO3/Ag
Voc=1.642 V
Jsc=14.35 mA/cm2
FF=73.7%
PCE=17.3%

PFN-Br finds application in a wide range of areas:
  • OPV interficial layer (metalic oxide compact layer)
  • OLED electron transport layer
  • Perovskite solar cells
  • Flexible printed electronics
  • Cationic polymer electrolyte
  • Anion exchange material
  • Light emitting electrochemical cells

其他说明

Recommend to use 0.2 mg/ml concentration for electron-transport interfacial layer in OPV.
