Relationship Between I3 2 Diffusion in Titania Nanopores Modified with Dyes and Open Circuit Voltage of Dye-Sensitized Solar Cell

Relative diffusion rates (Rrel) of I3 of polar atoms such as O or F decreased Rrel and open circuit voltage (Voc) of dye-sensitized solar cells (DSC). The results were explained by the fact that slow diffusion of I3 species in nanopores increases opportunities of charge recombination between elec-trons in titania layer and I3
