    • 2 with solvent A and rinsed by toluene, the τ of the DSC was shorter than that rinsed by AN. The result implies that the shorter Τ is not due to the different adsorption conditions of the dyes. This topic will be addressed further elsewhere.

    • This is valid if at least the DOS is not altered by the dye adsorption. The capacitance is also related to the plot of electron density vs V oc, thought the integration of capacitance with respect to voltage

    • Reference 43 reports that electron transfer from FTO to I 3- is significant for DSC using organic dyes, and it was suppressed largely by introducing a compact layer on the FTO. We have checked the influence of TiCl4 treatment on nanoporous TiO2 electrode, and a similar effect was seen between MK3 and N719 Figure S7, Supporting Information, suggesting the recombination from FTO is not the reason for the lower Voc in the case of DSC/MK3. We have checked also the effect of the compact layer for our samples and observed the non-negligible recombination from the FTO when the electron density becomes lower than 2 × 1017 cm-3. Under these conditions, the electron lifetime and Fermi level are underestimated. Above the electron concentration, little influence was seen

    • oc with shortest lifetime under the standard electrolyte, whereas MK3 showed the lowest Voc with electrolyte containing only LiI (Table S1, Supporting Information). These show different interactions of these dyes with electrolytes. Influence of tBP for the case of organic dyes is also interesting but this topic will be addressed elsewhere.
