An electrochromic device and application thereof

Abstract

The present invention relates to an electrochromic device (100). The electrochromic device (100) comprising a first conducting layer (110) comprising a first glass substrate (111a) that is surface-treated with a first electrode (111b); a second conducting layer (120) comprising a second glass substrate (121a) that is surface-treated with a second electrode (121b); a middle layer (130) deposited in between the first conducting layer (110) and the second conducting layer (120), wherein the middle layer (130) comprising an electrolyte layer (131) that is contained by spacers (132), wherein the electrolyte layer (131) comprising a viscous solid polymer electrolyte (SPE) made up from a combination of polymethacrylate (PMMA), propylene carbonate (PC), lithium perchlorate (LiClO4) and acetonitrile (ACN); and an electrochromic layer (133) disposed at the lower surface of the electrolyte layer (131), wherein the electrochromic layer (133) comprising tungsten trioxide (WO3) films.
