Development of thermoelectric silicide materials and modules forpower generation

The application of thermoelectric technology in the industrialwaste heat recovery sector is gaining increasing attention due tothe significant environmental benefits. Mg- and Mn-basedsilicides are promising high-performance thermoelectric materialsdue to their relatively high Seebeck coefficients, good electricalconductivity, and low thermal conductivity.

In addition, thesecompounds are composed of earth-abundant and environmentallyfriendly elements, and they are suitable for mid-temperaturethermoelectric applications. This presentation covers the synthesis of selected silicides as wellas the development of thermoelectric modules based on n-typemagnesium silicide and p-type manganese silicide. Key aspectssuch as material optimization and performance, metallization andbonding methods, and overall module performance are addressed.
