Thumbnail image of graphical abstract

Extended donor-acceptor oligothiophenes exhibit a narrow optical energy gap in combination with strong light absorption and good intermolecular π–π stacking in the solid state for efficient charge transport. Bilayer photovoltaic devices utilizing these oligomers as p-type semiconducting photosensitizers afford high power conversion efficiencies of up to 2.7%.
