Summary
An integrated photonic solar reflector and thermal emitter consisting of seven layers of HfO2 and SiO2 that reflects 97 per cent of incident sunlight while emitting strongly and selectively in the atmospheric transparency window demonstrates that the cold darkness of the Universe can be used as a renewable thermodynamic resource, even during the hottest hours of the day.
