How to use Low-E coating to achieve lower transition temperature and higher energy saving effect of thermochromic perovskite smart windows?

Thermochromic smart windows have become a new type of building energy-saving technology because they can passively respond to external temperature changes to achieve intelligent color change (that is, the glass is transparent when the weather is cold, and the glass is tinted when the weather is hot)

Recently, the research group of Cao Zhiyin of City University of Hong Kong proposed a perovskite smart window that can activate thermochromism at room temperature by absorbing the mid-near infrared rays of sunlight

The related work was published in the internationally renowned journal Advanced Science (IF: 16.

Liu Sai, a doctoral student at City University of Hong Kong, is the first author, Li Yang, a postdoctoral researcher at Hong Kong University of Science and Technology, is the co-first author, and Cao Zhiyin, an assistant professor at City University of Hong Kong, is the corresponding author
