Abstract: This work unveils a diffusion‐kinetic modulation strategy that fundamentally redefines sodium management in kesterite photovoltaics, enabling spatially controlled Na sequestration within Cu2ZnSn(S,Se)4 (CZTSSe) absorber layers through a thermally engineered “Na‐locking” mechanism. By establishing critical correlations… read more here.
