Photovoltaic (PV) technology is one of the most promising solutions to alleviate the energy crisis. Over 80% of solar energy dissipating as heat, negatively affects PV systems efficiency. Passive integrated adsorption system for PV Cooling and Atmospheric Water Harvesting (APVC/AWH) has recently been proposed to address this issue. An adsorbent on PV panel backside captures atmospheric moisture during night-time and release it during day-time by absorbing the PV panel waste heat, reducing its temperature and enhancing the efficiency. The desorbed moisture is collected producing freshwater. Effective implementation of the APVC/AWH system can only be solved through smart designing the adsorbent, whose properties are consistent with specific operating and climatic conditions (temperature, humidity) of region where the system is installed. Composite sorbents, based on hygroscopic Salts embedded into Porous Matrices (CSPMs) hold great promise for APVC/AWH due to a large adsorption capacity and tunability of the adsorption properties. The aim of this work is the systematic screening of numerous salt hydrates and selection the most promising ones for development of new CSPMs specialized for APVC/AWH. An approach to salt/hydrate selection for APVC/AWH is proposed, based on the calculation and analysis of standard enthalpy and entropy of the formation of numerous salt hydrates. Several salts (NiCl2, Na3PO4, Na2CO3, MgSO4) are selected for APVC/AWH in different climates. The CSPMs based on these salts are synthesized and tested to assess their potential for APVC/AWH. In a broader sense, the suggested approach to salt selection may be useful for the analysis of various adsorption applications.
