Title:
ELECTROCHROMIC DEVICE AND ELECTROCHROMIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/175941
Kind Code:
A1
Abstract:
The present invention relates to an electrochromic device having an improved color changing speed. The present invention provides an electrochromic device comprising: a first transparent electrode; a second transparent electrode facing the first transparent electrode; a first bus electrode of a predetermined pattern formed on an upper surface of the first transparent electrode; an electrolyte layer positioned between the first bus electrode and the second transparent electrode; a first electrochromic layer positioned between the first transparent electrode and the electrolyte layer and coming in contact with the electrolyte layer; and a passivation layer formed between the first bus electrode and the electrochromic layer so as to prevent contact of the first bus electrode and the electrochromic layer, and encompassing the first bus electrode. According to the present invention, the electrochromic speed of a large area electrochromic device can be improved.
