Electrochromic device with functions of rapid switching duty cycle and infrared suppression

In this paper, the electrochromic device with functions of rapid duty cycle and infrared (IR) suppression. The electrochromic device is simultaneously not only having high optical modulation but also IR-suppression by using the multilayered AZO/Ag/AZO structure. The AZO/Ag/AZO structure is using to be transparent electrode and the nano-crystalline WO
₃
is using to be electrochromic layer. The electrochromic device showed an optical modulation (ΔT) at a wavelength of 550 nm was 74.8 %, which is the difference between the transmittance of the colored state (14.61 %) and that of the bleached state (89.36 %). The response time of the device is found to be about 11.9 s for colored state and 6.8 s for bleached state.
