Abstract
Electrochromic devices comprise first and second conductors, wherein at least one of the first and second conductors is a multi-layered conductor. The electrochromic devices further comprise an electrochromic stack between the conductors adjacent to a substrate. The at least one multi-layered conductor comprises a metal layer sandwiched between a first non-metal layer and a second non-metal layer such that the metal layer does not contact the electrochromic stack.
Claims11
An electrochromic device comprising, in the following order:
- a) a glass substrate;
- b) a first transparent conductive oxide layer;
- c) a first defect mitigating insulating layer;
- d) a first metal layer;
- e) a second defect mitigating insulating layer;
- f) an electrochromic stack comprising a cathodically-coloring electrode layer and an anodically-coloring electrode layer sandwiching an ion conductor layer;
- g) a second transparent conductive oxide layer;
- h) a second metal layer;
- and
- i) a third transparent conductive oxide layer.
An electrochromic device comprising, in the following order:
- a substantially transparent substrate;
- a first multi-layer conductor disposed on the substantially transparent substrate, the first multi-layer conductor comprising, in order, one or more color tuning layers, a first metal layer, and a first defect mitigating insulating layer;
- an electrochromic stack;
- and
- a second multi-layer conductor disposed on the electrochromic stack, the second multi-layer conductor comprising, in order, a second defect mitigating insulating layer and a second metal layer.
