Utilizing hygroscopic hydrogels for the passive cooling of PV panels presents a simple and effective method. The hygroscopic hydrogel captures atmospheric water vapor during nighttime, and throughout the daytime, the solar-induced heat on the surface of the PV panels is conducted back to the hydrogel cooling layer, triggering water evaporation.

Theoretically, water vapor sorption by CaCl2 takes place in two stages, i.e. hydration and deliquescence of CaCl2. While the evaporation/desorption of the sorbed water is driven by the heat from PV panel during daytime. Stage 1: hydration Reaction formula CaCl2+H2O—CaCl2·H2O.

The high heat-to-vapor efficiency from interfacial evaporation enables the PV-SWE to have a higher performance than most previous evaporation cooling technologies (5.9°C–9.6°C), even better than floating PV systems that are installed on water bodies (11.7°C–14.5°C).

The gel—a mix of carbon nanotubes in polymers with a water-attracting calcium chloride salt—causes the vapor to condense into droplets that the gel holds. When heat rises during the day, the gel releases water vapor. If covered by a clear plastic, the released vapor is trapped, condenses back into liquid water, and flows into a storage .
