A Novel Approach and Exergy Analysis for a Concentrated Photovoltaic System for Thermoelectric Absorption Cooling

A unique and distinctive absorption-thermoelectric cooling system powered by a photovoltaic-thermal unit is presented in this work with a thorough exergy analysis. The photovoltaic module supplied electricity to the thermoelectric cooler, while heat energy fueled the absorption unit. The solar module's efficient cooling enhances electrical output while diminishing the quality of thermal energy. Consequently, the thermoelectric cooler exhibits superior cooling performance compared to the absorption cooler. The primary objectives of the study are the coefficient of performance, exergy efficiency, and cooling capacity of the photovoltaic-thermal absorption system. A mathematical representation of the suggested system is shown. The model is assessed at a local solar irradiance of 1000 W/m² and various operational temperatures. The system coefficient of performance climbed from 0.67 to 0.73, while the exergy efficiency declined from 0.34 to 0.17 as the photovoltaic-thermal temperature rose from 60 to 120 °C, achieving a peak cooling capacity of 6 kW.
