Abstract
The present invention relates to an electrochromic device comprising a protective inorganic solid electrolyte film and a manufacturing method thereof. The electrochromic device comprises an electrochromic layer, an electrolyte layer and a counterelectrode layer, in which an inorganic solid electrolyte film as a protective layer is provided on the interface between the electrolyte layer and at least one layer of the electrochromic layer and the counterelectrode layer. The electrochromic device has excellent durability, fast bleaching and coloring response rates, and excellent memory effect with time. Accordingly, it can be advantageously applied to a commercial process for manufacturing electrochromic devices.

9. A method for manufacturing an electrochromic device, comprising the steps of:
-
a) depositing an electrochromic layer on a substrate having a transparent electrode layer formed thereon and then depositing an inorganic solid electrolyte on the electrochromic layer by a sputtering process so as to form a protective film;
b) depositing a counterelectrode layer on a substrate having a transparent electrode layer formed thereon and then depositing an inorganic solid electrolyte on the counterelectrode layer by a sputtering process so as to form a protective film; and
c) injecting an electrolyte between the electrochromic layer and the counterelectrode layer, which comprise the protective inorganic solid electrolyte films formed in the steps a) and b), respectively, so as to form an electrolyte layer. - View Dependent Claims (10, 11)
