Exciton dissociation at a poly(p-phenylenevinylene)/C_60 heterojunction

摘要

We report measurements of the photovoltaic effect in heterojunction structures consisting of a layer of C_60 thermally evaporated onto a film of the conjugated polymer poly (p-phenylenevinylene) (PPV) sandwiched between electrodes of indium-tin oxide and Al. Peak quantum efficiencies of up to about 9
