| Outline of Final Research Achievements |
The photon energy conversion interface of dye-sensitized solar cells, titanium oxide (TiO2)/dye/electrolyte interface, has been successfully investigated by using time-resolved spectroscopic method, especially transient absorption and transient grating technique. The transient absorption spectra of dye-sensitized solar cells showed temporal shift due to the interaction between absorbed dyes on the interface and ions in electrolyte, depending on the functional group of dyes and the absorbed manner of them. The surface enhanced Raman spectra of absorbed dyes has also been successfully observed by forming self-assembled metal nanoparticles monolayer on the interface。The obtained Raman spectra included the information about the structure of absorbed dyes, which could use for the evaluation of absorption manner of dyes.
