Sustainable Rejuvenation of Scalable Large-Area WO3-PB Electrochromic Devices
Electrochromic devices (ECD) have become a hot research topic in the field of green buildings due to their excellent energy efficiency and thermal management capabilities. Currently, challenges such as difficulties in large-area preparation, high costs, and degradation of electrochromic performance over time have hindered their widespread application. A strategy incorporating a dual-phase nanocrystalline structure of WO3 and TiO2·H2O is proposed, in which specific synthesis parameters are precisely controlled to tailor the microstructure and composition of the films, enabling the fabrication of large-area WO3-PB ECD with UV-rejuvenation electrochromic performance. As a result, the as-prepared WO3-PB ECD exhibits an optical modulation of 75.6% and a remarkable cycle life exceeding 13,000 cycles. The electrochromic performance degradation caused by long cycles can be restored via UV irradiation. Utilizing UV light to restore the performance of these WO3-PB ECDs promotes sustainable and environmentally friendly development, highlighting their important practical value.
