摘要：

We describe photoinduced charge transfer process in a bilayer device comprised of poly(p-phenylene vinylene) (PPV) layer and a trap-free molecularly doped polymer containing diaryldiamine (TPD) dispersed in polycarbonate (PC). The time resolved charge transfer from PPV to TPD:PC in the presence of an electric field is analyzed. The injection (transfer) efficiency of the photoinduced holes from PPV into TPD:PC is about 25% holes/photons at electric fields at 4 X 10(5) V/cm or higher. Minimal trapping of photocarriers at the interface region between the two polymer layers is associated with this transfer.
