    • In case of the electrode deposited from ANS-AN mixture, absorbance at 400 nm is relatively low (0.61) compared to the films prepared from the other solvent mixtures, because some parts of the deposited film inevitably exfoliate when pulled up from the cluster solution after completion of the electrophoretic process. However, the photocurrent generation efficiency based on the number of absorbed photons is calculated to be 3.3%, which is smaller than the IPCE value of the electrode prepared from BZN-AN (4.5%). Hence, given the high light-harvesting efficiency at 400 nm in the other deposited films, the light-harvesting efficiency is not a major factor determining the photocurrent generation in the present systems.

    • X-ray photoelectron spectroscopy measurements on the deposited film samples did not reveal any peaks originating from remaining solvents (e.g., Cl, in the case of the sample prepared from DCB-AN mixture). Therefore, we can rule out any possible effects of residual solvents on electron mobility
