An illustration of thermoelectric devices using a wavelength-selective emitter and a broadband emitter

Caption

An illustration of thermoelectric devices using a wavelength-selective emitter and a broadband emitter. The device using a broadband emitter experiences a voltage drop due to environmental temperature changes, while the device with a selective emitter remains constant thanks to daytime radiative cooling.
