bias voltage of 0.8 V. From Fig. 14, it is clear that the nature of Nyquist plots for all
devices are semicircle in nature. In the equivalent circuit, R CT represents the recombination charge transfer resistance of the cell and R-CPE is the resistance-constant
phase model. The value of R S and R CT are 57.74 and 750.79 , respectively, as
obtained from Fig. 14.
