General description
Application
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.
