Thermodynamic Control over the Competitive Anchoring of N719 Dye on Nanocrystalline TiO2 for Improving Photoinduced Electron Generation

TiO2 electrodes, sensitized with the N719 dye at high immersion temperatures during the sensitization process, were found to have large fractions of weakly bound N719 on the electrode surface, which resulted in dye aggregation and decreased device longevity. These disadvantages were ameliorated usin...
