Assessment of Ruthenium Dye N719 Adsorption Kinetics in Mesoporous TiO₂ Films of Dye-Sensitized Solar Cells via Nanoplasmonic Sensing

Figure 4

(a) Nanoplasmonic peak shifts upon injection of N719 dye into TiO₂ photoelectrode sintered at 200°C and 500°C. (b) Nanoplasmonic peak shifts of N719 dye in TiO₂ photoelectrodes of varying thicknesses from 700 nm to 775 nm. (c) Initial dye adsorption slope of the thinner films (700 nm film removed from data).
