Ultradurable Dye-Sensitized Solar Cells under 120°C Using Cross-Linkage Dye and Ionic-Liquid Electrolyte

Figure 6

Absorption spectra of double-bond-edged Ru-dye (SG1051) adsorbed nanocrystalline-TiO₂ electrodes without heating (a) and after the heating on a hot plate at 125°C (b) and 250°C (c). Each dyed electrode was dipped in NaOH aq. and acetonitrile successively, and the difference of absorbance was checked.
