Heat is an inevitable outcome in energy consumption processes, as more than 65% of input energy is wasted as heat. If we can generate electricity from waste heat, it will help minimize the needs for fossil fuels in power plants and can…

Thermoelectric (TE) devices have been attracting increasing attention because of their ability to convert heat directly to electricity. To date, improving the TE figure of merit remains the key challenge. The advent of the topological…

In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 $\mu$m can reach lower temperatures compared to broadband emitters, but broadband emitters always have higher…
