Abstract

This study aims to design and evaluate the performance of a hybrid photovoltaic–thermoelectric (PV–TEG) power generation system by integrating a heat sink and radiation reflector under various thermal management conditions. The objective of this study was to investigate the combined effect of these two methods on the power output and system efficiency without expanding the PV installation area. The experimental setup encompassed five configurations (A–E) comparing natural convection, thermoelectric modules, addition of reflective panels, and active cooling using either air suction or forced air ventilation. The experimental findings indicate that all PV–TEG configurations yielded higher power output and greater efficiency than the standalone PV systems. Notably, Configuration E, which combined radiation reflection with forced-air cooling, achieved the highest performance, increasing the electrical output by approximately 1.27 watts and reaching a peak efficiency of approximately 28.6%. The integration of the TEG modules contributed an additional maximum of 2.2% to the total energy output by harvesting excess thermal energy. Further analysis revealed significant correlations between solar irradiance, temperature and electrical efficiency. These results highlight the potential of PV–TEG hybrid systems to effectively harness both solar and thermal energy, particularly in high-temperature and high-irradiance environments.
