Abstract
Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically-insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer. The interfacial region contains an ion conducting electronically-insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices.

53. An electrochromic device comprising a stack comprising one or more cathodically tinting electrochromic layers comprising an electrochromic material and one or more anodically tinting counter electrode layers comprising a counter electrode material, wherein the stack was fabricated by a process comprising:
-
(a) depositing the one or more cathodically tinting electrochromic layers or the one or more anodically tinting counter electrode layers on a substrate; (b) depositing the other of the one or more cathodically tinting electrochromic layers and the one or more anodically tinting counter electrode layers deposited in (a), without depositing any other layer therebetween; and
then(c) depositing lithium metal on the stack to expose at least one of the cathodically tinting electrochromic layers and the one or more anodically tinting counter electrode layers to lithium. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. An electrochromic device fabricated by a process comprising:
-
(a) forming either an electrochromic layer comprising an electrochromic material or a counter electrode layer comprising a counter electrode material; (b) forming an intermediate layer over the electrochromic layer or the counter electrode layer, where the intermediate layer includes an oxygen rich form of at least one of the electrochromic material and the counter electrode material, and wherein the intermediate layer is not substantially electronically-insulating; and (c) converting at least part of the intermediate layer to a region, coextensive with the area of the intermediate layer, the region comprising an electronically-insulating, ionically-conductive material and the material of the intermediate layer. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86)

87. An electrochromic device comprising a cathodically tinting electrochromic layer comprising an electrochromic material and an anodically tinting counter electrode layer comprising a counter electrode material, wherein the electrochromic device was fabricated by a process comprising:
-
(a) depositing one of the electrochromic layer and the counter electrode layer on a substrate; (b) depositing the other of the electrochromic layer and the counter electrode layer directly on the layer deposited in (a), without depositing any other layer therebetween, wherein the electrochromic layer and the counter electrode layer contact one another; and (c) forming an ion conductive electronically insulating material at the interface of the electrochromic layer and the counter electrode layer after (a) and (b). - View Dependent Claims (88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108)
