1. An integrated photovoltaic (PV) panel-water sorption layer system comprising:
a PV panel having a front face that is configured to receive solar light for generating electrical current, and a back face that is opposite to the front face;
an atmospheric water harvesting device attached to the back face of the PV panel, the atmospheric water harvesting device including:
a water sorption layer formed directly on the back face of the PV panel, and
a cover lid that together with the back face of the PV panel form a sealed chamber; and
an actuation device connected to the cover lid and configured to move the cover lid to unseal the sealed chamber so that ambient air enters inside the sealed chamber,
wherein the water sorption layer is placed in the sealed chamber, and
wherein the atmospheric water harvesting device is configured to cool down the PV panel by evaporating absorbed atmospheric water based on heat received from the PV panel.
