Energy-Efficient Liquid Crystal Smart Window with
In this study, we enhance the angular-selective light absorption capabilities of guest–host liquid crystal (GHLC) cells by introducing a
Cholesteric liquid crystal coatings enable transparent, unidirectional solar concentrators compatible with modern windows. Scientists have created a transparent solar coating that turns ordinary windows into clean energy generators without affecting clarity.
Credit: Shutterstock A research team led by Nanjing University has introduced a transparent, colorless, and unidirectional solar concentrator that can be directly coated onto standard window glass.
Utilizing cholesteric liquid crystal (CLC) multilayers with submicron lateral periodicities, this diffractive-type solar concentrator (CUSC) selectively guides sunlight toward the edge of the window where photovoltaic cells are installed. The study appears in PhotoniX.
However, the challenge with static smart windows lies in their perennial opaqueness, regardless of the incident angle of sunlight. This limitation has spurred research into alternative solutions, and one such innovation is the application of guest–host liquid crystal (GHLC) cells [ 21, 22 ].
