CityUHK researchers develop mask-inspired perovskite smart windows to enhance weather resistance and energy efficiency

Description

Thermochromic perovskite is a new color switch material used in energy-saving smart windows. Despite its potential for energy savings, thermochromic perovskite suffers from poor weather resistance, susceptibility to water damage, and high optical haze, limiting its practical application. To overcome these challenges, researchers from City University of Hong Kong (CityUHK) developed a breathable, weather-resistant, low-haze perovskite smart window inspired by medical masks, pushing forward the wide applications of smart windows in green buildings.
