Cu2ZnSnSe4 thin films obtained by co-evaporation of components using an electron beam evaporation system were investigated by scanning electron microscopy, X-ray analy-sis, PIXI and RBS methods. The analysis of the diffraction patterns showed that the films are almost single-phased and contain mainly CZTSe compound, which has a tetragonal kesterite lattice type. The samples have textural growth of [211]. The lattice parameters of the material varied in the range of a = (0.56640-0.56867) nm, s = (1.13466-1.13776) nm, c/2a = 0.9983-1.0017 which correlate well with the reference data in a stable phase CZTSe compounds. From our PIXE analyses we assessed the influence of the growth conditions on the samples' chemical composition and mapped the surface distribution.
