摘要

基于可逆金属电沉积的动态窗户是提高建筑能效的一种有吸引力的方式,并显示出巨大的商业潜力。当两个电极接触时,依赖液体电解质的动态窗口有短路的风险,尤其是在较大规模下。在这里,我们开发了一种具有85%透射率的聚乙烯醇(PVA)凝胶聚合物电解质(GPE),也就是说,其硬度足以用作隔膜。GPE被实现在具有与使用液体电解质的窗口相当的电化学和光学性质的窗口中。此外,GPE能够在没有短路的情况下制造具有双工作电极(WE)和中心金属网对电极的窗口。我们的双WE-PVA-GPE窗口在101秒内达到0.1%的透射率状态,是具有一个工作电极(207秒)的液体窗口速度的两倍多。此外,双WE-GPE窗户的每一侧都可以单独着色,以展示不同的光学效果(即更具反射性或更具吸收性),为用户和智能建筑系统提供对单个设备架构中窗户外观和性能的更大控制。

Gel polymer electrolyte for reversible metal electrodeposition dynamic windows enables dual-working electrodes for faster switching and reflectivity control
Dynamic windows based on reversible metal electrodeposition are an attractive way to enhance the energy efficiency of buildings and show great commercial potential. Dynamic windows that rely on liquid electrolytes are at risk of short circuiting when two electrodes contact, especially at larger-scale. Here we developed a poly (vinyl alcohol) (PVA) gel polymer electrolyte (GPE) with 85% transmittance, that is, sufficiently stiff to act as a separator. The GPE is implemented into windows that exhibit comparable electrochemical and optical properties to windows using a liquid electrolyte. Furthermore, the GPE enables the fabrication of windows with dual-working electrodes (WE) and a metal mesh counter electrode in the center without short-circuiting. Our dual-WE PVA GPE window reaches the 0.1% transmittance state in 101 s, more than twice the speed of liquid windows with one working electrode (207 s). Additionally, each side of the dual-WE GPE window can be tinted individually to demonstrate varied optical effects (i.e., more reflective, or more absorptive), providing users and intelligent building systems with greater control over the appearance and performance of the windows in a single device architecture.
