Impact of the Dopant Species on the Thermomechanical Material Properties of Thermoelectric MgSiSn.

Thermoelectric generators are an excellent option for waste heat reuse. Materials for such devices have seen their thermoelectric properties improving constantly. The functioning of a generator, however, does not only depend on thermoelectric properties.

Overcoming Asymmetric Contact Resistances in Al-Contacted Mg(Si,Sn) Thermoelectric Legs.

Thermoelectric generators are a reliable and environmentally friendly source of electrical energy. A crucial step for their development is the maximization of their efficiency. The efficiency of a TEG is inversely related to its electrical contact resistance, which it is therefore essential to minimize.

Developing Contacting Solutions for MgSiSn-Based Thermoelectric Generators: Cu and NiCu as Potential Contacting Electrodes.

Magnesium silicides can be used for thermoelectric energy conversion as high values of figure of merit zT were obtained for n-type (1.4 at 500 °C) and p-type (0.55 at 350 °C) materials.
