photocurrent spectroscopy [9]. Later on, DiCarmine and Semenikhin study the mechanism and kinetics of carrier extraction of solar cells by intensity modulated photocurrent spectroscopy [10]. Recently, Kavasoglu et al. report the interaction of free carriers of solar cells by intensity modulation short circuit current spectroscopy [11].
This work proposes a new method to determine dynamic parameters by treating a solar cell as a 2-port network.
