Description
Kesterite-type based thin film solar cell technologies are mainly based on polycrystalline absorber layers. A promising low cost alternative technology uses Cu$_{2}$ZnSn(S,Se)$_{4}$ (CZTSSe) monograins (single crystals of 50-100 μm size) fixed in a polymer matrix to form a flexible solar cell.
In this study we tackle the influence of grinding the monograins on the stoichiometry deviation, the Cu/Zn disorder as well as intrinsic point defects and optoelectronic properties of CZTSSe monograins.
