摘要：
An electrochromic device is structured to restrict moisture permeation between an electrochromic stack in the device and an external environment. The electrochromic device includes conductive layers and one or more encapsulation layers, where the encapsulation layers and conductive layers collectively isolate the electrochromic stack from the ambient environment. The encapsulation layers resist moisture permeation, and at least the outer portions of the conductive layers resist moisture permeation. The moisture-resistant electrochromic device can be fabricated based at least in part upon selective removal of one or more outer portions of at least the EC stack, so that at least the encapsulation layer extends over one or more edge portions of the EC stack to isolate the edge portions of the EC stack from the ambient environment. The encapsulation layer can include one or more of an anti-reflective layer, infrared cut-off filter, etc.
