| Outline of Final Research Achievements |
At first, we facilitated the conformal deposition of Cu, In in nanoporous film consisted of TiO2 particles with the diameter of 25 nm via supercritical fluid deposition method. Secondary, we developed novel chalcogenization process using safe, low-cost and solid chalcogen sources instead of toxic gaseous chalcogen sources using supercritical ethanol as a reaction medium having high solubility and reduction power. By using these supercritical fluid processings, we succeeded in the conformal deposition of CuInS2 in nanoporous TiO2 film, and realized a promising 3D solar-cell structure with CuInS2.
