employed by radio frequency sputtering at the interface between ITO and porous-TiO2.
Effects of the absence and presence of the TiO2 layer were mainly investigated by means of
incident photon-to-current efficiency (IPCE), open-circuit voltage decay (OCVD) and
electrochemical impedance spectroscopy (EIS). The sensitization effect of N719 dye has
been improved due to the right-shifted transmittance spectra as shown by IPCE …
