Abstract

This paper deals with developing an analytical equation for the TEC combined with a PVT air collector. The PVT-TEC air collector produces thermal and electrical energy. The integration of TEC on the bottom side of the PV panel reduces the temperature of the PV cell, and then the system's overall efficiency is increased. For the analysis of the air collector, the input variables, namely solar irradiance and atmospheric temperature, have been taken for April month at Shiv Nadar Institution of Eminence (SNIOE), Gautam Buddha Nagar, India. The air collector has been modelled using MATLAB 2022a to find the temperature of PV cell, TEC, and collector outlet temperatures. After finding all temperatures, we can calculate the PVT-TEC air collector's overall electrical, thermal, and exergy efficiency. The results show how a characteristic curve varies with the thermal, electrical, and exergy efficiency. The 𝜂𝑒𝑙 and 𝜂𝑒𝑞,𝑡h was found to be 11.77 – 14.17 % and 42.21 – 48.18 %, respectively. Further, the overall exergy varied from 12.24 – 14.62 %.
