China’s transparent coating to turn ordinary windows into solar power generators | The transparent solar concentrator uses liquid crystal films to harvest energy.
Chinese researchers have developed a transparent solar window that turns buildings into clean energy generators without affecting visibility.
This semi-transparent solar concentrator uses liquid crystal films to reflect and guide circularly polarized sunlight, enabling colorless energy harvesting for next-generation green buildings. The innovation, which was designed by a research team at Nanjing University in the Chinese province of Jiangsu, uses cholesteric liquid crystal (CLC) multilayers with submicron lateral periodicities. “By engineering the structure of cholesteric liquid crystal films, we create a system that selectively diffracts circularly polarized light, guiding it into the glass waveguide at steep angles,” Dewei Zhang, PhD, a researcher at Nanjing University and first author of the study, disclosed.
