Kopsavilkums

We have studied influence of Cu₂ZnSnSe₄ (CZTSe) and secondary phases of Cu₂S and SnS on optical properties of kesterite-type Cu₂ZnSnS₄ (CZTS) by using the effective medium theory. We found that CZTSe and Cu₂S cause band gap reduction and enhance light absorption of CZTS at all photon energies of the sunlight whereas SnS changes optical properties of CZTS only at large photon energies beyond the solar spectrum. Optical spectra of CZTS(Se) has been studied by first principles calculations within hybrid functional that was used as input for the effective medium theory.
