The synthesis of unsymmetrical triphenylamine‐oligothiophene hybrid conjugated systems bearing dicyanovinyl electron acceptor end‐groups is presented. When used as molecular donor materials in solution‐processed bulk heterojunction solar cells, these compounds lead to efficient devices with very high open‐circuit voltages.
