1,6-Dithiophenol-substituted perylene organic sensitizer 1 was synthesized, and its photovoltaic properties in dye-sensitized solar cells were assessed. When anchored onto TiO2 film, the dye exhibits an unprecedented incident monochromatic photon-to-current conversion efficiency of 87 % and yields a power conversion efficiency of 6.8 % under standard AM 1.5 solar conditions.
