Abstract :
In this work we investigate electric properties of CdS/CdTe solar cells subjected to nitric-phosphoric (NP) etching procedure, employed for the formation of Te-rich layer before back contacting. The etching time has been used as the only variable parameter in the study, while admittance spectroscopy (AS) was employed for the characterisation of the cells´ electric properties-as well as for the analysis of the defect energy levels and densities
