摘要：

A poly(p-pyridyl vinylene)(PyV)/poly(3-hexylthiophene)(P3HT) heterojuction photovoltaic cell was fabricated and its photoirradiation effects have been investigated. Quenching of photoluminescence both in the PPyV and P3HT layers has been observed in the PPyV/P3HT heterojunction film. The photovoltaic characteristics of the hetreojunction photovoltaic cell are also greatly improved from those in a P3HT monolayer photovoltaic cell. Its photoresponse gives evidence of die photoinduced charge transfer between PPyV and P3HT. These results are discussed by taking account of the difference in electronic states of both PPyV and P3HT.
