Abstract

The growing demand for energy-efficient buildings requires advanced smart window technologies capable of dynamically modulating solar radiation. Here, we propose a reversible electrodeposition and electrochromic mirror (RECM) system that actively controls both visible (light) and near-infrared (NIR) (heat) radiation to regulate indoor conditions while ensuring glare-free, pedestrian-friendly operation. This system achieves voltage-tunable optical transitions among three distinct modes: transparent (Mode I), visible-blocking (Mode II), and visible + NIR-blocking mirror state (Mode III). When installed in a miniature model house, the RECM effectively suppresses the indoor temperature rise by mitigating NIR penetration. The incorporation of complementary electrochromic chromophores (Prussian blue and 1,1′-diheptyl-4,4′-bipyridinium dibromide) reduces glare by absorbing visible light reflected from the mirror-side, overcoming a key limitation of conventional mirror-containing platforms that restricts their use on building façades. With adaptive solar control, enhanced energy efficiency, and pedestrian-friendly, antiglare performance, the RECM represents a promising next-generation smart window technology for sustainable urban environments.

无眩光，节能智能窗户：具有动态可调光和热调节的行人友好系统

对节能建筑日益增长的需求需要能够动态调节太阳辐射的先进智能窗户技术。在这里，我们提出了一种可逆电沉积和电致变色镜（RECM）系统，该系统主动控制可见光（光）和近红外（NIR）（热）辐射，以调节室内条件，同时确保无眩光，行人友好的操作。该系统在三种不同的模式之间实现电压可调的光学跃迁：透明（模式I），可见阻塞（模式II）和可见+ nir阻塞镜像状态（模式III）。当安装在微型样板房时，RECM通过减少近红外穿透有效地抑制室内温度上升。互补电致变色发色团（普鲁士蓝和1,1 ' -二烷基-4,4 ' -二溴联吡啶）的结合通过吸收从镜子侧面反射的可见光来减少眩光，克服了传统的含镜子平台限制其在建筑立面上使用的关键限制。RECM具有自适应太阳能控制，提高能源效率，对行人友好，防眩光性能，代表了可持续城市环境中有前途的下一代智能窗户技术。
