Numerical analysis of energy conversion in a PV-TGS (mSi-Bi 2 Te 3 ): A based approach in materials simulation

A simulation model was developed to determine the power generated by a Photovoltaic-Thermoelectric Generation System (PV-TGS). The model yielded results that differed from those previously reported by other authors for PV panels and cells by a range of -0.017% to +1.74%. In thermoelectric production, the results deviated by a range of -2.27% to -2.80%. The model was formulated based on the constitutive equations of the phenomena inherent to the photovoltaic generation of a monocrystalline silicon PV panel (mSi) and the thermoelectric generation of bismuth telluride (Bi2Te3) Thermoelectric Generators (TEG). The primary variables of interest were irradiance (G), panel operating temperature (TPPV), and the cold section of the TEG (Tc), as well as the generated electrical power (P). The research outcomes enabled the determination of the optimal number of TEGs for the PV-TGS design, considering the temperature difference between the TPPV and Tc sections.

Highlights PV-TGS simulation from manufacturing materials presents a compelling alternative for forecasting electrical power output. Forecasting the electrical energy generation of a PV-TGS enables the determination of the optimal number TEGs. There are equivalent PV-TGS based on the Tc and the TPPV. The utilization of TEG presents a viable alternative to enhance the performance of photovoltaic systems.
