Applicazioni

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

Altre note

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