“…The smaller the diameter of the semicircle in a Nyquist plot, the lower the resistance and the quicker the rate of transfer of photogenerated charge carriers. 37,38 The arc radius in PCZ reduced as compared to the host and filler materials, indicating that the rate of charge recombination and charge transformation was faster than that in pure materials. Figure 13d showed the cyclic voltammetry of the PC, ZnS, and PCZ at a scan rate of 100 mV/s.…”
