Abstract: Various embodiments may include methods of controlling a temperature of an electrochromic device. The methods may include determining a current temperature of the electrochromic device which includes a first transparent conductor electrically connected to a working electrode, and a second transparent conductor electrically connected to a counter electrode, and applying the heating current to the first transparent conductor and the second transparent conductor if the current temperature is below a minimum temperature to heat the electrochromic device. Further embodiments may include an electrochromic system including an electrochromic device and a controller configured to control the temperature of the electrochromic device.

Abstract: An electrochromic system and method for controlling photochromic darkening of an electrochromic device, the system including an EC device, a control unit, a voltage detector, and a power supply. The EC device includes a working electrode, a counter electrode, a solid-state polymer electrolyte disposed therebetween, and a Bragg reflector configured to selectively reflect UV radiation away from the working electrode. The control unit is configured to control a sweep voltage applied between the working and counter electrodes, such that the sweep voltage is applied when an open circuit voltage (OCV) between the working and counter electrodes is less than a threshold voltage.

Abstract: An electrochromic device may include a working electrode that includes a high temperature stable material and nanoparticles of an active core material, a counter electrode, and an electrolyte deposited between the working electrode and the counter electrode. The high temperature stable material may prevent fusing of the nanoparticles of the active core material at temperatures up to 700° C. The high temperature stable material may include tantalum oxide. The high temperature stable material may form a spherical shell or a matrix around the nanoparticles of the active core material. A method of forming an electrochromic device may include depositing a working electrode onto a first substrate, in which the working electrode comprises a high temperature stable material and nanoparticles of an active core material, and heat tempering the working electrode and the first substrate.
