The key to the breakthrough lies less in the material itself than in how it was shaped. 3 watts per square metre under solar irradiance of 1,000 W/m². That opens the door to applications ranging from façades and roofs of buildings to electronic devices, vehicles and even personal cooling systems, all with the same goal: reducing dependence on air conditioning and the emissions that come with it.
