摘要

The carbon-rich layer at the back-contact interface of a solution-processed Cu2ZnSn(S,Se)4 (CZTSSe) absorber is investigated with a combination of surface-sensitive X-ray photoelectron and bulk-sensitive X-ray emission spectroscopy. For absorber deposition, an aqueous ammonium-thioglycolate (ATGL) solution was used, and the “buried” back-contact interface was accessed by cleaving in a liquid nitro...
