Fabrication of a Silicide Thermoelectric Module Employing Fractional Factorial Design Principles

Abstract Thermoelectric modules can be used in waste heat harvesting, sensing, and cooling applications. Here, we report on the fabrication performance of a four-leg module based abundant silicide materials. While previously optimized Mg 2 Si 0.3 Sn 0.675 Bi 0.025 is as n -type leg, employ fractional factorial design Taguchi methods mapping out four-dimensional parameter space among Mn x-? Mo ? 1.75?? Ge ? higher manganese compositions for p material. The assembled using scalable process, Cu metallization layer Pb-based soldering paste. maximum power output density 53 ?W cm –2 achieved at hot-side temperature 250 °C difference 100 °C. This low thermoelectric related to high contact resistance between materials metallic contacts, underlining importance improved schemes assembly.
