Pt/Mesoporous Carbon Counter Electrode with a Low Pt Loading for High-Efficient Dye-Sensitized Solar Cells
Figure 6
Electrochemical impedance spectra of the symmetric thin-layer cell consisting of two identical Pt/MC electrodes taken at zero bias, ac amplitude 10 mV, the electrolyte containing 0.5 M KI/0.05 M I2 in the mixture of EC and PC (EC:PC = 2:8 by volume).
