Current Status of Nanostructured Thermoelectric Materials for Mid-High Temperature Applications
Year: 2019
Type: article
Abstract: Thermoelectric energy conversion has attracted much attention because it can convert heat into electric power directly through solid state device and vice versa.Current research is aimed at increasing the thermoelectric figure of merit (ZT ) by improving the power factor and reducing the thermal conductivity.Although there have been significant progresses in increasing ZT of material systems composed of Bi, Te, Ge, Pb, and etc. over the last few decades, their relatively high cost, toxicity, and the scarcity have hindered further development of thermoelectrics to expand practical applications.In this paper, we review the current status of research in the fields of nanostructured thermoelectric materials with eco-friendly and low cost elements, such as skutterudites and oxides, for mid-high temperature applications, highlighting the strategies to improve thermoelectric performance.
