Abstract

A low band gap polymer based on the copolymerization between benzodithiophene and thieno-pyrroledione units has been investigated in both conventional and inverted polymer bulk-heterojunction photovoltaic cells. High power conversion efficiencies of more than 4% in both device structures were demonstrated.
