Abstract
A self-heating electrochromic device and related manufacturing methods are provided. The electrochromic device includes a bottom electrode layer and a bottom substrate attached to each other; a top electrode layer and a top substrate attached to each other; an electrochromic layer, an electrolyte layer, and a charge storage layer sandwiched by the bottom electrode layer and the top electrode layer. Two first high conductive bars may be respectively provided on two edges of the bottom electrode layer, and two second high conductive bars may be respectively provided on two edges of the top electrode layer. The first and second high conductive bars may be configured to generate a current in the electrode layer in response to a voltage, and thus increase the temperature of the electrochromic device, thereby improving the switching speed of the electrochromic device in a low temperature environment.
