Advanced Nickel Oxide Based Materials for Electrochromic Applications

The optical transmission and/or optical reflectivity of electrochromic coatings can be varied repeatedly and reversibly between low and high transmission states, and/or between low and high reflectivity, by applying an electrical potential between the top surface and bottom surface of the electrochromic coating. In the specialized application to architectural windows, or windows comprising the exterior envelopes of buildings, electrochromic coatings on the window glass can be used to control the amount of sunlight and/or solar heat that enters the building. This control can extend from ultraviolet wavelengths into the infrared, to modulate the entire solar spectrum of sunlight that typically reaches habitable buildings.
