Hydrothermal Synthesis and Evaluation of the Cu2ZnSnS4 for Photovoltaic Applications [PDF]

Materials Research, 2021
The research focused on the hydrothermal synthesis of a material based on a Kesterite structure of Cu2ZnSnS4 (CZTS). For this purpose, the component cations, in concentrations of 1.0 molL-1, were placed in a steel autoclave under different temperatures conditions (200, 220, 240, 260 and 280°C) for 32 h. After, the solids were calcined at 400°C for 2 h.
