  • Patent number: 10353262
    Abstract: The present invention discloses a method for fabricating an electrochromic device, which adopts the vacuum cathodic arc-plasma deposition to comprise five layers with an ionic conduction layer (electrolyte) in contact with an electrochromic (EC) layer and an ion storage (complementary) layer, all sandwiched between two transparent conducting layers sequentially on a substrate. The method owns superior deposition efficiency and the fabricated thin film structures have higher crystalline homogeneity. In addition, thanks to the nanometer pores in the thin film structures, the electric capacity as well as the ion mobility are greater. Consequently, the reaction efficiency for bleaching or coloring is enhanced.
