This work describes a procedures to grow single phase Cu 2 ZnSnS 4 (CZTS) thin films with tetragonal-kesterite type structure, using solution and vacuum based deposition techniques. The solution based deposition approach involves sequential deposition of Cu 2 SnS 3 (CTS) and ZnS films, where the CTS compound is synthesized in one step process by simultaneous precipitation of Cu2S and SnS 2 performed by diffusion membranes assisted CBD technique and the vacuum based approach includes sequential evaporation of the elemental metallic precursors under a flux of sulphur supplied from an effusion cell. X-ray diffraction analysis (XRD) which is mostly used for the phase identification can not clearly distinguish the formation of secondary phases such as Cu 2 SnS 3 , since both compounds have the same diffraction pattern; therefore the use of a complementary technique is needed. Raman scattering analysis was used to distinguish these phases. Further, the chemical elemental composition and oxidation states of both type of CZTS films were studied by X-ray photoelectron spectroscopy (XPS) analysis. |
