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.
