The I2-II-IV-VI4 series of quaternary chalcogenides semiconductors have drawn wide interest for their potential application as solar-cell absorbers; In this paper, we present a study of electronic and optical properties of the equilibrium kesterite structure (KS) of Cu2ZnSnS(Se)4 (CZTS(Se)), stannite structure (SS) of Cu2ZnSnS4 and secondary phases of KS-Cu2ZnSnS4 in the DFT frame. For this purpose, we used the Wien2k code based on the density functional theory (DFT) with the modifiedfatcat:jqnsxzjb3rhtlolapaqo5dx5rm
