The authors of the new work used electrochromic technology , which is used to obtain a material that
We showed the very first electrochromic device that can switch between solar heating and radiation cooling.
Po-Chun Hsu is an assistant professor in the Department of Mechanical Engineering and Materials Science at Duke University.
Smart electrochromic glass is a relatively new technology that uses an electrochromic reaction that changes the glass from transparent to opaque and back again.
The authors of the new work showed a thin device that interacts with both spectra of light and switches between passive heating and cooling modes.
In heating mode, the device dims to absorb more sunlight.In cooling mode, it becomes lighter and begins to reflect sunlight.
Such a material cannot be transparent, so it will not fitIt is better to use it to cover the surface of the building, they noteAuthors.
