Radiative cooling: A review of fundamentals, materials

As shown in Fig. 23, for the silicon-based PV–PT–RC system, photons with energy higher than 1.1 eV (for silicon solar cell) will be partly converted to electricity, while the remaining absorbed photons will be transformed into heat. Moreover, cooling energy and/or space cooling can be obtained via nocturnal radiative cooling.
