Films of solid solutions of Cu 2 Mg x Zn 1-x SnS 4 (x = 0.1; 0.2; 0.3; 0.4) were obtained from precursors with different zinc and magnesium concentrations ratios by spray pyrolysis. Their structural characteristics and chemical composition have been studied. X-ray diffractometry method showed that Mg atoms are successfully embedded in the material's crystal lattice. The resulting layers contain up to 9% magnesium and have a kesterite structure. This statement is confirmed by Raman spectroscopy. Analysis of the results shows an improvement in the structural characteristics of the layers with an increasing concentration of Mg atoms embedded in the crystal lattice of the material. Therefore, the films of solid solution Cu 2 Mg x Zn 1-x SnS 4 are a promising material for the absorbing layers of the third-generation solar cells.
