Abstract
Polymer solar cells are a fascinating low cost alternative to silicon-based solar cells1 thanks to light weight, mechanical flexibility and processability. The polymers suitable for this purpose should possess good filming and absorption properties (absorption coefficients >105 cm-1 and UV–Vis spectrum ideally matching the solar spectrum)2, high hole mobility, and HOMO–LUMO energy levels suitable to be coupled with the acceptor species3. In this presentation the synthesis of three different low band gap copolymers is reported and discussed. The properties of these materials are compared in order to gain an insight on the molecular structure-performance relationship of the final device
