Abstract

In the paper, we study the influence of the tunneling effect recombination inside the interface absorber/ CdS and the effect of surface treatment in the absorber of solar cell CIGS Cu-rich. This study will be done with neutrals defects and charged defects. Whatever the charge of the defect, we noted that the cell efficiency decreases with this recombination and increases with the surface treatment. We have also observed that this surface treatment is more efficient and the recombination by tunnel effect is much more harmful when the defects are charged.
