Quaternary compounds with a tetrngonal lattice, like Cu2Zn(Sn,Ge)(S,Se)4, are considered as promising for photovoltaic application [1,2]. The Raman scattering analysis showed high potential to identify secondary phases in quatema1y compounds [1,2]. In addition its application to single c1ystals allows to increase the knowledge on fundamental vibrational prope1iies of studied materials. Single c1ystals of Cu2ZnSnSe4, Cu2ZnSnS4 and Cu2ZnGeSe4 were grown by chemical vapor transpo1i method and orientation of biggest c1ystal plane was determined by rotating X-ray diffraction method. The non-polarized spectra presented at Fig. 1, showed the expected similarities in the peak position for all compounds. Analysis of polarized Raman spectra in the dependence of c1ystal orientation angle allowed to detennine the symmetry of the most observed peaks (15 for Cu2ZnSnSe4, 19 for Cu2ZnSnS4 and 16 for Cu2ZnGeSe4 from 27 possible modes for kesterite type structure). The peaks symmetry assignment allowed confmning the kesterite type structure for all compounds and analysis of angular dependence of intensity for different peaks yielded the relative values of Rainan tensor elements.
