With a little more context I can draft a suitable article or summary for you.

For example:

When combined with a thermoelectric generator, the sustained temperature differential can be converted directly into electrical power. Early prototypes (RCTD‑001 to RCTD‑020) demonstrated proof‑of‑concept but were limited by low radiative cooling fluxes (< 60 W m⁻²) and insufficient TE performance at modest ΔT (< 5 °C). Recent advances in metasurface engineering, low‑thermal‑conductivity substrates, and high‑ZT TE materials have paved the way for a new class of devices.
