| Synonyms | Poly(9,9-bis(3'-(N,N-dimethyl)-N-ethylammoinium-propyl-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene))diBromide, OS0995, PFN-P2 |
| Molecular Formula | (C56H80N2.Br2)n |
| Flash Point | Not applicable |
| Appearance | beige to yellow solid |
| Application | 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 VJsc=14.35 mA/cm2FF=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 layerPerovskite solar cellsFlexible printed electronicsCationic polymer electrolyteAnion exchange materialLight emitting electrochemical cells |

| Description | 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.[3] 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.
