Bridge the gap: Rigid π-conjugated bridges such as the ethynyl spacers, are effective for connecting the phthalocyanine π system to the conduction band of TiO2. A series of zinc phthalocyanine photosensitizers with carboxyethynyl anchoring groups have been synthesized. Solar cells sensitized with the pictured compound exhibit record efficiencies of 5.5 % and 6.1 % under 100 (1 sun irradiation) and 9.5 mW cm−2, respectively.
