Abstract: Exergy analysis of a thermodynamic system is carried out to identify sources, causes and magnitude of both reversible and irreversible losses and its usefulness as a tool in improving the performance of a system. Herein, an exergy analysis of a novel concentrated photovoltaic-thermoelectric system is presented. Results showed that losses increase with increase in the optical concentration ratio and at high optical concentration ratio; it is more beneficial to lower the efficiency temperature coefficient than to increase the energy conversion efficiency of the photovoltaic system.

Keywords: concentrator; copper plate; exergy efficiency; hybrid system; irreversibilities; microchannel heat sink; optical concentration ratio; reference efficiency; photovoltaic; temperature coefficient; thermal resistance; thermoelectric module.
