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

Figure 4

Influence of the porosity (thin contour) and percentage of macropores (thick contour) on the kinetics of dye uptake for the AO (triangle), PEG 0 (circle), PEG 10 (square), and PEG 30 (diamond).
