A large amount of thermal energy that emitted from many industrial processes and social activity of mankind is available as waste heat. By converting heat directly into usable electricity, thermoelectric (TE) generators can offer a very promising environment friendly technology for waste heat recovery. The key to realize an efficient TE generator lies, however, in finding good materials with high thermoelectric performance, good durability at high temperature, and preferably robustness on operating in air. The performance of a TE material is evaluated by the dimensionless figure-of-merit ZT (= S2T/ρκ , where S, T, ρ, and κ are the Seebeck coefficient, absolute temperature, electrical resistivity, and thermal conductivity, respectively). In this talk, the recent progress in developing materials and thermoelectric generator devices for high temperature thermoelectric power generation is presented (Fig. 1). Besides, other thermoelectric activity at the Department of Energy Conversion and Storage will be also introduced.
