Near‐Infrared‐Activated Thermochromic Perovskite Smart Windows (Adv. Sci. 14/2022)

Smart Windows In article number 2106090 by Sai Liu, Chi Yan Tso, and co‐workers, a self‐activated thermochromic perovskite smart window is developed. This window demonstrates a passive color‐switch ability between cold and hot weathers. Notably, the window can smartly harvest the near‐IR by the photothermal layer to trigger the thermochromism at room temperature, showing great potential for use as a new generation window technology in buildings.
