Abstract

In this work, we studied the influence of the doping rate of the CIGSe layer on the recombination-generation mechanisms with 25 nm incorporation of a KF layer on a CIGSe solar cell. The different doping taken are Nb=1015cm-3, Nb=1016cm-3 et Nb=1017cm-3. Numerical modeling with the SCAPS-1D software shows that the generation rate varies slightly while that of recombination is very important, explained by a strong presence of traps in the CIGSe bandgap.
