Tungsten oxide is an electrochromic material, so tungsten oxide electrochromic film can be used as an electrochromic layer to assemble an electrochromic device. According to experts, under a certain voltage, an electrochromic device combines an electrochromic material such as WO3 film and an electrolyte to achieve a reversible change in color, thereby controlling the transmission of light.

So, do you know why electrochromic device is worn out? After long-term use, the electrochromic devices can be worn out or to be unusable. And it is mainly caused by solid phase physical changes or chemical side reactions. In addition, if the voltage difference applied in the cycle is too large, the cycle life of the device will also be shortened. And therefore, it is generally not switched between the maximum capacities of the electrochromic devices during use. All in all, cycle life is an important parameter to evaluate the performance of electrochromic devices.
