Optoelectronic Investigation of Sb-Doped Cu(In, Ga)Se2
Abstract
Doping Cu(In,Ga)Se2 (CIGS) thin films with Sb can provide large grains at lower processing temperatures than are normally required. In this study, we incorporated Sb into the precursor of a two-step selenization process. We saw enhanced grain size and improved device performance compared to similarly processed CIGS films made without Sb. The optoelectronic properties of the Sb-doped CIGS films were examined with photoluminescence (PL) and admittance spectroscopy. These techniques allowed us to evaluate the origin of a lower-energy PL peak that is not typically seen in CIGS.
