Figure 8
Nyquist plots of DSSCs based on Z3T0, Z3T1, Z3T3, and Z3T5 samples as the photoanodes under illumination of 100 mW/cm2 (AM 1.5) and AC amplitude of 10 mV. The data points are from experiments, and the solid lines are the fitting results according to the equivalent circuit shown in the inset.
