Thermo-chemistry guided synthesis of Cu2ZnSnSe4 compounds using solvo-thermal method

We report a design of synthesis routes from thermodynamic principles using FactSage and a fabrication of Cu2ZnSnSe4 via a solvo-thermal method. To suppress the sublimation of Se, we use binary compounds of high vaporization temperature by first converting Se into liquid-like alloys. Finally, the single-phase Cu2ZnSnSe4 composites are successfully synthesized.
