Article Synopsis
- This study focuses on the local atomic structure of off-stoichiometric kesterites, specifically Cu2ZnSnS4, Cu2ZnSnSe4, and Cu2ZnGeSe4, highlighting how deviations from ideal composition affect their properties as solar cell materials.
- Researchers employ Extended X-ray Absorption Fine Structure Spectroscopy to analyze bond stretching force constants and examine changes in bond lengths related to off-stoichiometry at different temperatures.
- The findings reveal systematic trends in bond lengths, particularly in Cu-Se and Zn-Se bonds, providing insights into the influence of point defects on the materials' local structure and their implications for electronic properties in solar applications.
