摘要

电致变色器件(ECD)以其优异的能效和热管理能力成为绿色建筑领域的研究热点。目前,大面积制备困难、成本高、电致变色性能随时间下降等挑战阻碍了它们的广泛应用。提出了一种结合WO3和TiO2·H2O双相纳米晶结构的策略,通过精确控制特定的合成参数来定制薄膜的微观结构和组成,从而制备出具有紫外回火电致变色性能的大面积WO3- pb ECD。结果表明,制备的WO3-PB ECD具有75.6%的光调制率和超过13000次的显著循环寿命。由于长时间循环导致的电致变色性能下降可以通过紫外线照射恢复。利用紫外线恢复这些WO3-PB ECDs的性能,促进了可持续和环保的发展,突出了其重要的实用价值。

Sustainable Rejuvenation of Scalable Large-Area WO3-PB Electrochromic Devices

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.
