To determine the influence of NaF/KF-post-deposition treatments (PDT) on the chemical and topographical surface structure of Cu(In,Ga)Se2 (CIGSe) solar cell absorbers, we have used synchrotron-based hard x-ray photoelectron spectroscopy (HAXPES) and scanning electron microscopy (SEM). Variations of the PDT parameters can be used to tune thickness and degree of surface nanopatterning; here we find that the nanopatterning is more pronounced on CIGSe surfaces having more potassium and less copper… CONTINUE READING
