Evaluation Through Numerical Modeling of the Performance and Economic Parameters in a Hybrid System with a Photovoltaic Cell and Thermoelectric Generator

The current investigation is carried out by constructing a numerical model to analyze a hybrid PV-TEG system. The model considers the influence of temperature on the thermoelectric properties of construction materials used in thermoelectric generators. For the development of the study, variables such as solar concentration, environmental factors and convective heat transfer coefficient, environmental mitigation, and economic savings in the hybrid PV-TEG system are evaluated. The results obtained demonstrate an increase of 4.65% in the efficiency of the hybrid PV-TEG system due to the improvement in the solar concentration ratio. Increased ambient temperatures can cause a 1.74% reduction in system efficiency. However, the increase in wind speed allows an increase of 4.39%. The higher convective heat transfer coefficient favors the performance of the hybrid PV-TEG system. Implementing this type of technology can lead to reductions in CO2 emissions by 0.45 kg/h and a decrease in economic costs by 0.024 USD/h. In general, the hybrid PV-TEG system is considered a strategy for the carbon-free energy transition.
