Abstract
We describe photoinduced charge transfer process in a bilayer device c omprised of poly(p-phenylene vinylene) (PPV) layer and a trap-free mol ecularly doped polymer containing diaryldiamine (TPD) dispersed in pol ycarbonate (PC). The time resolved charge transfer from PPV to TPD:PC in the presence of an electric field is analyzed. The injection (trans fer) efficiency of the photoinduced holes from PPV into TPD:PC is abou t 25% holes/photons at electric fields at 4 X 10(5) V/cm or higher. Mi nimal trapping of photocarriers at the interface region between the tw o polymer layers is associated with this transfer.
