TiO 2 -CuInS 2 is one of the promising materials for 3D nanocomposite solar cells. To utilize for 3D nanocomposite solar cells, TiO 2 -CuInS 2 should well deposited onto transparent conducting oxide such as indium doped tin oxide (ITO). High pressure coating with liquid carbondioxide ( l -CO 2 ) was successfully deposited TiO 2 -metals chalcogenide onto ITO substrate. Further heat treatment (oxidation and sulfurization) lead the formation of CuInS 2 from metals chalcogenide deposited on the mesoporous TiO 2 . The formation of CuInS 2 on the was confirmed by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and Raman spectroscopy. The atomic ratios of deposited CuInS 2 were nearly stoichiometric after sulfurization. The crystal growths of CuInS 2 were controlled by adjusting the number of coating cycles.
