Improved energy conversion of a photovoltaic module‐thermoelectric generator hybrid system with different cooling techniques: Indoor and outdoor performance comparison

Abstract

Numerous studies have emphasized the role of cooling in maximizing the energy conversion efficiency of a photovoltaic (PV) module. Amongst them, the energy and exergy analyses of PV-thermoelectric generator (PV-TEG) hybrid systems with evaporative cooling have been rarely investigated. Hence, the present experimental study focuses on the performance comparison of PV-TEG hybrid system with different cooling techniques. The parameters studied are panel temperature, energy and exergy efficiency, power output, and I-V and P-V characteristics. As the indoor and outdoor radiation spectrum varies
