Highly Efficient Mesoscopic Dye‐Sensitized Solar Cells Based on Donor–Acceptor‐Substituted Porphyrins

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 TiO2 film. A greatly enhanced photovoltaic performance is observed when the porphyr... View More
