Abstract
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/cm2 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 × 106 cycles, suggesting that Eosin Y was fairly stable unless UV light was irradiated.Keywords
