Unsymmetrical Triphenylamine‐Oligothiophene Hybrid Conjugated Systems as Donor Materials for High‐Voltage Solution‐Processed Organic Solar Cells

Abstract

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.
