Thermoelectric generator (TEG) technologies and applications

Nowadays humans are facing difficult issues, such as increasing power costs, environmental pollution and global warming. In order to reduce their consequences, scientists concentrating on improving generators focused energy harvesting. Thermoelectric (TEGs) have demonstrated capacity transform thermal directly into electric through the Seebeck effect. Due unique advantages they present, thermoelectric systems emerged during last decade a promising alternative among other technologies for green production. this regard, device output prediction is important both determining future use of new technology specifying key design parameters systems. Moreover, TEGs environmentally safe, work quietly do not include mechanical mechanisms or rotating elements can be manufactured broad variety substrates silicon, polymers ceramics. addition, position-independent, long working life ideal bulk compact applications. Furthermore, been found viable solution direct generation electricity from waste heat in industrial processes. This paper presents in-depth analysis TEGs, beginning with comprehensive overview principles effect, Peltier Thomson effect Joule heating applications, materials used, Figure Merit, improvement techniques including different material arrangements used substrate types. performance simulation examples COMSOL Multiphysics ANSYS-Computational Fluid Dynamics investigated.
