Cost-effective route to quaternary Cu2ZnSnS4 nanostructured powder fabrication was developed by utilizing a two-step approach. In the first stage, nanostructured binary sulfides Cu2S, ZnS, and SnS were synthesized by chemical bath deposition. In the second stage, ternary sulfide Cu2ZnSnS4 was obtained by low-temperature annealing of binary sulfides’ mixtures at 70 and 300 ◦C. The compounds obtained on both stages were investigated by X-ray diffraction, scanning electron microscopy, optical absorbance and Raman spectroscopy. On the basis of our findings, we established that Cu2ZnSnS4 phase has already formed at 300 ◦C. The synthetic pathway revealed in this work allows reducing the temperature of Cu2ZnSnS4 synthesis and as a result, offers the possibility of reducing the manufacturing costs. This work was supported by the Russian Foundation for Basic Research (grant No. 16-03-00566), UrB RAS (grant No.15-20-3-11).
