This New Solar Panel Tech Works Even at Night
Thermoradiative energy generation – often dubbed “nighttime solar” or “anti-solar” power – is a new way to generate electricity after the sun goes down. It exploits a simple scientific principle: heat flows from warmer objects to cooler surroundings, and that flow can be converted into electricity. During the day, the Sun warms the Earth; at night, the Earth’s surface cools by radiating heat as infrared light into the cold darkness of space. Thermoradiative devices aim to tap into this outgoing heat radiation and turn it into usable power nature.com abc.net.au. In essence, they act like solar cells in reverse: instead of absorbing sunlight from a hotter source, they emit infrared light to a colder sink to drive an electric current nature.com unsw.edu.au. As long as the device is warmer than its environment, it will radiate heat and can produce electricity from that energy flow nature.com abc.net.au.
