Glass windows now store energy, says groundbreaking research.

February 12, 2024

Researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have developed a transparent battery that can transform glass windows into energy-storing devices. The battery uses aluminium-ion battery technology and has colour modulation capabilities, making it suitable for use in smart windows. During the day, the windows remain transparent and allow sunlight into the room, while simultaneously storing energy. At night, the stored energy can power electronic devices and the windows transition to a dark blue state to provide privacy. The battery is cost-effective, high-performing, and safe, thanks to the use of aqueous electrolytes. The researchers believe this technology has significant potential for integration into smart window applications and are seeking collaboration with smart glass manufacturers for commercialisation.
