Cu₂Sn_1-xSi_xS₃ (CTSiS) is promising material for non-expensive and non-toxic absorber layer of thin films solar cells. However, CTSiS have not been fabricated high-quality films, and basic optical properties have not been investigated. Therefore, polycrystalline CTSiS was grown by solid state reaction, and observed photoluminescence to investigate basic optical properties.
