摘要：

Solar cell composed of Eosin Y-sensitized porous TiO2 electrode treated with TiCl4 showed remarkably high photon-to-current efficiency (51% at 533 nm) and solar-to-energy efficiency (1.3%, AM-1.5, 100 mW/cm(2) with UV cutoff filter). Eosin Y dimer supposed to be more efficient than monomer. Turnover number of Eosin Y for excitation was more than 2.7 x 10(6) cycles, suggesting that Eosin Y was fairly stable unless UV light was irradiated.
