Özet:

 

The present work reports some experimental results on the  electrical properties of high efficiency ZnO/CdS/Cu(In,Ga)Se2  heterojunction solar cells.  Admittance spectroscopy has been employed  for characterisation of the bulk and interface levels in the absorber  Cu(In,Ga)Se2 layer.  The temperature dependent capacitance-frequency  analysis indicated an emission from a shallow acceptor like defect  level with an activation energy of about 75 meV. Information on the  equivalent circuit model of the devices has been provided by the  analysis of impedance measurements.  The impedance data are presented  in the Nyquist plot at several dc bias voltages at 300 K. The  equivalent circuit model consisting of a parallel resistor and  capacitor in series with a resistor is found to give a good fit to the  experimental data.
