제목 New Mechanism of Photomultiplication Type Organic Photodiode Assisted by Perovskite Thin Layer
초록 Photomultiplication (PM) type organic photodiode (OPD) has a significantly higher external quantum efficiency (EQE) compared to traditional OPD and draws intensive attention. Unlike the conventional OPDs which convert light into electric charge, the absorption layer of PM-OPD requires additional acceptor at which minority charges are trapped. Here, we report thin perovskite film which induces photomultiplication without using acceptor. This phenomenon is expected as a result of minority charge trap induced by not only the energy level offset but also the band bending induced by ion-migration of the perovskite thin film.
