Abstract
Photoirradiation effects of a poly( p-pyridyl vinylene) (PPyV)/poly(3-hexylthiophene) (PAT6) heterojunction photocell have been investigated. The photovoltaic characteristics of the heterojunction photocell are considerably improved from those in a single-PAT6-layer photocell. Quenching of photoluminescence both in the PAT6 layer and in the PPyV layer has also been observed in the PPyV/PAT6 double layer. The observed photoirradiation effects of the heterojunction have been discussed in terms of interfacial photoinduced charge transfer between PAT6 and PPyV.Keywords
