Abstract
Abstract An electrochromic device, comprising: a first transparent electrode, an electrochromic layer, a macromolecular solid electrolyte layer and a second electrode, each applied successively, being characterized in that the macromolecular solid electrolyte layer is a plasma polymerization film which includes a hydrocarbon compound, an alkali metal and an element having large electronegativity. An electrochromic device, comprising, a transparent electode, an electrochromic material made from an organic material of the ion injection type, an ionic conductor layer, and a second electrode, each applied successively, wherein said electrochromic layer is a film which is made with a plasma polymerization process of a phthalocyanine compound under the supply of carrier gas at a low frequency between 1 kHz and 3 MHz of alternating electric field.
