'Night-time solar' technology can now deliver power in the dark
Innovative research from a UNSW team shows Earth’s radiant infrared heat can be used to generate electricity, even after the sun has set.
UNSW researchers have made a major breakthrough in renewable energy technology by producing electricity from so-called ‘night-time’ solar power.
The team from the School of Photovoltaic and Renewable Energy Engineering generated electricity from heat radiated as infrared light, in the same way as the Earth cools by radiating into space at night.
A semiconductor device called a thermoradiative diode, composed of materials found in night-vision goggles, was used to generate power from the emission of infrared light. (More)
