Paper Abstract

We introduce a laminate two-layer approach to electrochromic smart windows. It incorporates two glass panes, each having a two-layer coating, laminated by a transparent adhesive solid polymer electrolyte. Each coating has a transparent conducting base layer and a top layer of an ion insertion compound. We made ion-insertion layers of W03, V205 and NiOx by sputtering and evaporation. These layers were characterized by cyclic voltammetry in liquid electrolytes and by spectrophotometry. Our novel electrolyte comprised a methyl methacrylate network incorporating poly (propylene glycol) complexed with lithium perchlorate. Initial optical data are reported for laminated devices having an "active" electrochromic LixWO3 layer and a "passive" LixV205 counter electrode.
