Abstract :
In this article, we report fabrication and characterization of the photovoltaic devices using donor polymer-acceptor polymer composites and heterojunction. Upon mixing the two polymers, quenching of photoluminescence and improvement of photovoltaic properties have been observed. These phenomena have been interpreted in terms of the photoinduced charge transfer between donor and acceptor polymers. Drastic enhancement of photovoltaic effect has been observed also in the heterojunction device consists of donor and acceptor polymers. The charge carrier transport phenomena in polymer donor-acceptor composites have been studied by characterizing the field-effect transistors with the composites, and discussed in terms of the percolation model
