Photovoltaic Thermal Solar System in Presence of Nanofluid Cooling Analyzing Environmental Parameter in Existence of TEG Module

Current work delves into enhancing the productivity of a photovoltaic (PV) unit by incorporating a thermoelectric generator (TEG). The cooling mechanism employs a triangular-shaped duct with a ferrofluid, and magnetic force is employed to augment the cooling efficiency. Additionally, the model accounts for the impact of dust on the system's productivity. The efficiency components, namely ηth (thermal), ηTE (thermoelectric), and ηPV (electrical PV), have been evaluated across different ranges of ϕ (nanoparticle concentration), Ha (Hartmann number), and Vin (inlet velocity). These results have been obtained through rigorous numerical simulations, with a comprehensive validation test to ensure their accuracy and reliability. When accounting for the presence of dust particles, we observe a reduction in ηth, ηTE, and ηPV by approximately 3.98, 6.96, and 9.46
