Abstract

Ferroelectric P(VDF-TrFE) nanoparticles (NPs)with sizes of 60–100 nm are synthesized using a simple solution chemistry method. The preformed ferroelectric NPs enable the application in low bandgap polymers without the annealing process. The power conversion efficiency of the polyN-9′-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′benzothiadiazole) (PCDTBT)-based device reaches 6.7%, which is 25% higher than the optimized device with a low work function metal as cathode.
