Structural development and dynamic process in sulfurizing precursors to prepare Cu2ZnSnS4 absorber layer.

Highlights: [•] CZTS films were fabricated by sulfurizing the fabricated precursor films. [•] Annealing time and temperature are very important for synthesis of pure CZTS films. [•] Pure CZTS films with high quality can prepared at 500°C and 90min. [•] Both high temperature and long heating time causes the decomposition of CZTS films. [ABSTRACT FROM AUTHOR]
