Good Co-op: A novel cyclopentadithiophene-bridged donor–acceptor dye applied as sensitizer in mesoscopic dye-sensitized solar cells, in conjunction with the cobalt complexes [CoII(bpy)3](B(CN)4)2 and [CoIII(bpy)3](B(CN)4)3 as redox couple, yields high power conversion efficiencies (up to 9.6 %) under standard AM 1.5G solar irradiation. The results confirm that cobalt complexes are legitimate alternatives to the commonly used I−/I3− redox shuttle when used with judiciously engineered organic sensitizers.
