Utilization of biconvex lenses in the development of hybrid PV-TEG

Abstract

Solar energy is an essential renewable energy source, with the potential to address growing energy demands and reduce dependence on fossil fuels. However, traditional Photovoltaic (PV) systems have limitations in generating electricity efficiently, especially under high-temperature conditions. This study aimed to design and implement a circuit for a hybrid Photovoltaic-Thermoelectric generator (PV-TEG) that utilized biconvex lenses for sunlight concentration. Data, including the power of both PV and TEG and the weather conditions, were acquired and noted throughout the testing period. With the use of a mean test to analyze the system's performance and efficiency, the concept's efficacy demonstrates a system efficiency of 27.27-36.34%, which is greater than most standalone systems. When the PV was subjected to high temperatures from the sun, the TEG produced a significant amount of power output. This compensates for some of the inefficiencies of the PV component during high temperatures. The findings suggest that using biconvex lenses to develop hybrid PV-TEG is a promising approach for improving the efficiency and performance of solar energy systems.
