In other words, the decrease in electron injection yield from the dye to TiO2 electrode, which would be caused by decomposition or detachment of the dye molecule from the TiO2 electrode, was not the factor determining the decreased IPCE performance.In this report, as a review article we have summarized recent ultrafast spectroscopic studies on phenomena associated with dye-sensitization of semiconductor metal oxide nanoparticles, especially TiO2 nanocrystalline film from a surface science perspective with a strong relation to mechanism of electron injection in dye-sensitized solar cells, which are attracting much interest from both viewpoints of pure science and applied science.Although a lot of chemical and physical processes are involved in this solar cell, such as light harvesting by molecules and nanostructures, interfacial electron transfer, charge migration in solid and electrolyte, degradation of the materials, and so on, the very primary process initiated by photoabsorption by sensitizing dye molecules; that is, electron injection from excited adsorbates into the conduction band of semiconductor metal oxides is significantly important because this process must be 100% efficient with a minimum driving force for high current and voltage generation.
