Conclusion
In this paper, dynamic impedance of a DSSC is derived from the AC equivalent circuit and
experimental results. Impedance measurements are done by using a FRA under dark condition. The
nature of voltage and frequency dependent impedance of the DSSC is also illustrated. The dynamic
impedance of the DSSC can yield information and explain the parameter behaviors. The simple method
described in this paper can be used to investigate series, dynamic, and shunt resistance of DSSC.
Moreover, the dynamic impedances developed in this work can be further applied for the comparison of
the DSSC performance.
