A series of A-D-A-type oligothiophenes have been developed as efficient donor materials for application in vacuum-processed organic solar cells. Due to their promising optoelectronic properties and molecular packing in the bulk, these oligomers show high power conversion efficiencies up to 2.8% in planar heterojunction and record efficiencies of 5.2% in bulk heterojunction solar cells prepared by vacuum deposition.
