The influence of polymer purification on photovoltaic device performance of a series of indacenodithiophene donor polymers

Keywords

Indacenodithiophene polymers

Abstract

​A series of low bandgap indacenodithiophene polymers is purified by recycling SEC in order to isolate narrow polydispersity fractions. This additional purification step is found to have a significant beneficial influence on the solar cell performance and the reasons for this performance increase are investigated.
