Abstract:
1. An electrochromic device comprising: (a) an electrochromic layer comprising an electrochromic material; (b) a counter electrode layer comprising a counter electrode material; and (c) an interfacial region between the electrochromic layer and the counter electrode layer, wherein the interfacial region comprises a mixture of: (i) a substantially electronically insulating ion conductor material, and (ii) the electrochromic material, the counter electrode material and/or an additional material, where the additional material includes distinct electrochromic or counter electrode material, wherein the electrochromic material is operable for a first electrochromic transition, wherein the counter electrode material is operable for a second electrochromic transition, and wherein the electrochromic device has only one electrochromic layer and only one counter electrode layer.
