Abstract
Electrochromic devices are disclosed which may be used for large surface area applications. The devices utilize optical tuning to minimize optical interference between layers of the structure and to maximize uniform optical transparency. Optical tuning also enables transparent conductive oxide layers to be replaced by thin conductive metal layers, thereby reducing the overall thickness of these devices and facilitating the manufacturing process.
