Schematic of a thermoelectric generator (TEG) Image: Ken Brazier, Wikimedia Commons, CC BY-SA 4.0 DEED Researchers from India's Vellore Institute of Technology have developed an experimental system, coupling PV with a thermoelectric generator (TEG) and a graphite sheet as a heat dissipation element.
Each TEG consists of two ceramic layers of 0.5 mm and 2 mm, respectively. The academics tested the setup against a reference system consisting of a graphite sheet as a heat dissipation element. The graphite sheet, with a thickness of 0.05 mm, was pasted using the same adhesive to the heat dissipation side of the TEG.
“The fundamental purpose of this research is to integrate PV-TEG with graphite as a heat dissipator,” the academics explained. “TEG converts excess heat into electricity, while graphite increases heat dissipation and temperature difference.
Nonetheless, several studies throughout the years have established that temperature increase in PV cells result in efficiency decrease [7 10]. Hence, power output of a PV panel decreases with temperature increment. This is the reason for cooling devices as key component of an integrated hybrid generation system.
The assessment of the radiation heat model contemplates radiation emitted to the sky and radiation emitted to the ground from the front and rear faces of the PV panel. This, as seen before in the convective model, divides the heat flow into several components.
“TEG converts excess heat into electricity, while graphite increases heat dissipation and temperature difference. Therefore, a low-power PV panel backside glued with a TEG-graphite sheet has been tested and controlled to study this approach.”
