Room-temperature Deposition of Nano-TiO_2 Coating by Vacuum Cold Spraying Using TiCl_4-agglomerated Nano-TiO_2 Powder for Flexible Dye-sensitized Solar Cell

摘要

TiCl_4 treatment was used to chemically agglomerate TiO_2 primary nano-particles to form a nanostructured powder in size of submicrometer. Nanocrystalline TiO_2 coatings were fabricated by vacuum cold spraying at room temperature using the powder and were
