dc.description.abstract	Polycrystalline Cu2ZnSnS4-xSex (X=1, 2, 3) compounds were synthesized by conventional solid-state reactions. The samples were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray analysis (SEM-EDS), Raman spectroscopy, diffuse reflectance UV-vis and Photoluminescence. All ofphases crystallize in the tetragonal kesterite-type structure. The powder X-ray diffraction (XRD) pattems were indexed in the space group . No secondary phases were detected in XRD pattems. The results from diffuse reflectance show band gap between 1.26 - 1.17 eV, when S is gradually replaced by Se. The PL spectrum of Cu2ZnSnS4-xSex phases shows nearly symmetrical band, which shifted linearly to the lower energy with increasing Se content. The selenized (CZTSSe) phases are promising candidates to be used as absorbing material in solar cells.	es_CL
