Enhancing Photovoltaic-Thermoelectric Generator (PV-TEG) system performance via mathematical modeling and advanced thermal interface material: An emphasis on Pyrolytic graphite Sheet (PGS)

PV-TEG systems utilize waste heat by using TEGs under PV panels. TEGs improve the efficiency of PV and generates more energy. However, rough metal surfaces at contact points reduce the system's thermal efficiency and create air gaps. This paper employs a mathematical model based on principles o...
