Scientists from Saudi Arabia’s King Abdullah University of Science and Technology have developed a cooling solution for photovoltaic panels that uses a sorption-based atmospheric water harvester (AWH).
The device, which can be placed on the back of commercials PV panels, collects atmospheric water during the evening and at night. The collected water is then vaporized and released during the day using waste heat from the PV panel as energy source. The evaporation of the water in turn takes away a significant portion of heat from the panel itself and lower its temperature.
