Abstract
Impedance spectroscopy is widely applied for the characterisation of CdTe and CuInGaS thin film solar cells. We apply this method to verify the current transport in specific voltage and temperature regions where space charge limited current is the dominant conduction mechanism. A modified equivalent circuit is proposed under specific illumination and temperature conditions. The reasonable results assess that voltage dependency of capacitance and resistance in such cases might be modified. Such modified voltage dependency represents the relevant trap distribution of space charge limited current.
