To dye for : A porphyrin chromophore, which is integrated into a donor–acceptor dye as a π‐conjugated bridge (see picture), exhibits an unprecedented efficiency of 11 % when used as a photosensitizer in a double‐layer TiO 2 film. A greatly enhanced photovoltaic performance is observed when the porphyrin dye is cosensitized with a metal‐free dye that has a complementary spectral response.
