Abstract: In the present article, a PVT-TEC air collector integrated with an MMGHSD has been evaluated, and a mathematical model has been derived for finding distinct parameters, namely, the temperature of the solar cell, TEC, air from PVT-TEC, crop, and room. The outcome shows that with TEC, the electrical efficiency increased by 2.23% compared to basic PV. Further, the impact of air mass flow rate on energy, exergy, electrical, and thermal efficiency has been computed. The system's exergy and exergy efficiency were in the range of 18.91-65.55 Wh and 11.96-16.44%, respectively, for a 0.01 kg/s mass flow rate.

Keywords: photovoltaic thermal; PVT; thermoelectric cooler; TEC; mixed-mode greenhouse dryer; MMGHSD; energy; exergy efficiency; mathematical modelling.
