Ferroelectric coupling effects on the energy-band structure of hybrid heterojunctions are investigated using photovoltaic devices with poly(3-hexylthiophene-2,5-diyl) (P3HT)/ZnO and poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)). The self-organized P(VDF-TrFE):P3HT photoactive layer forms a novel architecture consisting P3HT domains in P(VDF-TrFE) matrix. at interface p–n heterojunction is tuned by artificial control ferroelectric polarization material, consequently modulating performance devices.
