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, and a solid-state polymer electrolyte disposed therebetween. 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.

Abstract: An electrochromic device includes a nanostructured transition metal oxide bronze layer that includes one or more transition metal oxide and one or more dopant, a solid state electrolyte, and a counter electrode. The nanostructured transition metal oxide bronze selectively modulates transmittance of near-infrared (NIR) spectrum and visible spectrum radiation as a function of an applied voltage to the device.
