A high-performance electrochromic device assembled with WO3/Ag and TiO2/NiO composite electrodes towards smart window
The choice of cathode and anode materials for electrochromic devices plays a key role in the performance of electrochromic smart windows. In this research, WO3/Ag and TiO2/NiO composite thin films were separately prepared by the hydrothermal method combined with electrodeposition. The electrochromic properties of the single WO3 thin film were optimized, and TiO2/NiO composite films showed better electrochromic performance than that of the single NiO film. WO3/Ag and TiO2/NiO composite films with excellent electrochromic properties were respectively chosen as the cathode and the anode to construct a WO3/Ag-TiO2/NiO electrochromic device. The response time (tc = 4.08 s, tb = 1.08 s), optical modulation range (35.91%), and coloration efficiency (30.37 cm2·C−1) of this electrochromic device are better than those of WO3-NiO and WO3/Ag-NiO electrochromic devices. This work provides a novel research idea for the performance enhancement of electrochromic smart windows.
