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

Figure 2

(a) IV and (c) quantum efficiency characteristic curves of devices fabricated with 3 μm mesoporous TiO₂ films using various ruthenium dyes N3, N749, Z907, and dye N719. (b) Absorbance at dye peaks on solid 3 μm mesoporous TiO₂ films show correlation with device quantum efficiency of respective dyes. Both device quantum efficiency in (b) and absorbance in (c) of dyes N3 and N749 show intersection at 585 nm.
