Researchers at The University of Texas at Austin have developed a new electrochromic device for smart windows using sustainable materials such as amylose from corn, potatoes, and beans. This innovation addresses the need for more sustainable and energy-efficient building solutions. Guihua Yu, a professor involved in the research, emphasized the importance of creating affordable, sustainable electrochromic materials and devices to facilitate the adoption of smart windows. The technology enables modulation of light transmission by over 85%, enhancing energy efficiency in buildings.
The device's resilience was proven through extensive testing, including over six weeks of UV exposure and thousands of usage cycles, without the need for metal ions or organic solvents. The market for smart glass is projected to grow significantly, although costs currently restrict broader adoption. Buildings are a major energy consumer in the U.S., with a significant portion of energy used for heating, ventilation, and air conditioning. The research, supported by various awards and involving international collaboration, is published in the Proceedings of the National Academy of Sciences.
