Thermoelectric Ceramics for Energy Harvesting

Abstract

Metal oxides (Ca 3 Co 4 O 9 , CaMnO 3 , SrTiO 3 , In 2 O 3 ), Ti sulfides, and Mn silicides are promising thermoelectric (TE) material candidates for cascade‐type modules that are usable in a temperature range of 300–1200 K in air. In this paper, we review previous studies in the field of TE materials development and make recommendations for each material regarding future research. Furthermore, the R&D of TE modules composed of metal oxide materials and the prospect of their commercialization for energy harvesting is demonstrated.
