Abstract
Photoinduced hole transfer between photoexcited x-conjugated polymer, poly(p-phenylene vinylene) (PPV) and an adjacent trap-free hole-transp ort molecularly doped polymer containing TPD in a polycarbonate binder in an electric field, is analyzed. Also analyzed and described, under similar electric field conditions, is photoinduced electron transfer between PPV and a trap-free electron transport polymer containing BCFM and a polycarbonate binder. Transfer of carriers, both holes and elec trons, to the respective transport layers is fast and coherent, withou t delay. The collection efficiency at an electric field of 4x10(5)Vcm( -1) is 25% for photoinduced holes and near 0.2% for photoinduced elect rons.
