Key Points

The aim is to explore how atomic structure and disorder affect the efficiency of Kesterite solar cells.
Utilized neutron powder diffraction to analyze Cu-poor/Zn-rich monograins.
Quantified Cu/Zn disorder and identified intrinsic point defects.
Focused on samples with S/(S+Se) ≈ 0.8.
Identified significant effects of Cu/Zn disorder on device efficiency.
Found correlations between intrinsic defects and solar cell performance.

Implication

Experimental investigation quantifies efficiency factors for Kesterite monograin solar cells, suggesting pathways for improvement.

Abstract

Cu-poor/Zn-rich Cu 2 ZnSn(S,Se) 4 (CZTSSe) monograins with S/(S+Se) = 0.8 were investigated using neutron powder diffraction to directly quantify Cu/Zn disorder and intrinsic point defects. According to their chemical composition, the monograins...
