Abstract: 
In this paper, the authors demonstrate a small prototype of a smart window based on the thermo-optical properties of cholesterol liquid crystals. Due to its polymer-free design, the manufactured smart window is transparent and can reflect certain portions of visible or infrared light without requiring an external power source, and thus is easier to install and operate. The proposed smart window technology based on a cholesteric liquid crystal mirror will reduce energy consumption costs by reflecting excess sunlight and heat transfer, increasing comfort for residents of buildings and structures.
