Cu 2 SnS 3 (CTS) nanoparticles were successfully synthesized by simple solvothermal technique maintained at 200°C for 24 h. The structural properties showed that the Cu 2 SnS 3 nanoparticles exhibit cubic phase with high crystallinity and a grain size between 11 and 15 nm. CTS nanoparticles exhibited a broad absorption in a wide wavelength range from UV to visible light, with a direct band gap of 1.27 eV. The electrical proprieties of the synthesized material show a variation of the conductivity as a function of measurement temperature. The dc sample conductivity measurements reveal that 3D-VRH is the dominated conduction model in the studied material. However, the dynamic conductivity study shows that correlated barrier hopping model may be appropriate to describe the transport mechanism in our material.

“…It is observed that the CTS film prepared using a concentration of Cu 2+ of 15 mM, exhibit Raman peaks at 289, 300, 335 and 353 cm -1 which have been assigned to the A' symmetry vibrational modes from the tetragonal Cu 2 SnS 3 phase. [20][21][22][23] In addition, this sample exhibits a peak at 315 cm -1 which also has been assigned to the monoclinic Cu 2 SnS 3 phase. However, other authors have observed peaks at 290, 314 and 352 cm -1 which were assigned to monoclinic Cu 2 SnS 3 .…”

This work reports results of a study carried out to optimize the preparation conditions of Cu 2 ZnSnS 4 (CZTS) thin films grown by sequential deposition of Cu 2 SnS 3 (CTS) and ZnS layers, where the Cu 2 SnS 3 compound was grown using a novel procedure consisting of simultaneous precipitation of Cu 2 S and SnS 2 performed by diffusion membrane assisted chemical bath deposition (CBD) technique. The precipitation across the diffusion membranes allows achieving moderate control of release of metal ions into the work solution favoring the heterogeneous growth mainly through an ion-ion mechanism. Through a parameters study, conditions were found to grow Cu 2 SnS 3 thin films which were used as precursors for the formation of Cu 2 ZnSnS 4 films. The formation of CZTS thin films grown in the Cu 2 ZnSnS 4 phase was verified through measurements of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. Solar cells with efficiencies of 4.9% were obtained using CZTS films prepared by membrane assisted CBD technique as absorber layer.
