TL;DR: In this article, the compositional dependence of the physical properties of CZTSSe alloys through first-principles calculations was studied and it was shown that these mixed-anion alloys are highly miscible with low enthalpies of formation.

TL;DR: In this paper, the evolution of structure and optical properties of CZTSSe powders with different S/Se ratios were investigated, which were synthesized by the solid state reaction method.

TL;DR: In this article, the results of energy dispersive X-ray spectroscopy (EDX) indicate that these CZTS thin films are Cu-rich and S-poor.

TL;DR: In this paper, the authors directly observed a complete transformation of perovskite MAPbI3 surface region energetics from p- to n-type during defect passivation caused by natural additive capsaicin.

TL;DR: In this article, the results of X-ray diffraction, Raman spectra, and scanning electron microscope (SEM) analysis indicate the internal compressive stress relaxes in post-annealed quaternary CZTS thin films.
