Abstract

In-situ investigations of Cu(In, Ga)(S, Se)2 (CIGS) absorber layers during growth have the potential to provide insight into the origin behind elemental segregation and defect formation at grain boundaries and in grain cores. Our study focuses on CIGS films grown by an industrially relevant precursor reaction process. An in-situ stage developed for these synchrotron studies is used to image the growth of CIGS layers with nanoscale resolution. Utilizing synchrotron based x-ray fluorescence, we are able to rapidly monitor changes in elemental distribution and particle diffusion, with better than 200 nm spatial resolution throughout the 25 minute process. In this work, we highlight some challenges associated with this type of measurements and discuss solutions identified to overcome them.
