Systems and methods for controlling electrochromic devices using integrated power source

Abstract

An electrochromic device comprising: an active electrochromic layer having optical properties that vary based on an electrical voltage applied to the active electrochromic layer; an integrated energy source integrated within the electrochromic device for generating or storing electrical energy; and a controller operatively coupled to the energy source and the active electrochromic layer for applying the electrical energy generated or stored by the integrated energy source to the active electrochromic layer to achieve the optical properties desired by a user. The described electrochromic device is entirely self-contained and internally produces all the electrical energy necessary for its operation and specifically for the operation of the controller and for controlling the optical properties of the electrochromic layer. In other words, there no external wiring or any kind is required for supplying electric energy to the electrochromic device.
