Effect of TiO₂ Photoanode Porosity on Dye Diffusion Kinetics and Performance of Standard Dye-Sensitized Solar Cells

Figure 5

Dye desorption of sintered TiO₂ films immersed for 30 mins to 24 hrs in a 3 mM solution of N719 dye in ethanol. The absorbance was corrected for the actual specific surface area of each film, where Corr. Abs = Abs./( × weight).
