The Mg2Si TE legs used in our module were fabricated by a plasma-activated sintering method using material produced from molten commercial doped polycrystalline Mg2Si, and, at the same time, nickel electrodes were formed on the Mg2Si using a monobloc plasma-activated sintering technique. The source material used for our legs has a ZT value of 0.77 at 862K. The TE modules, which have dimensions of 21mm×30mm×16mm, were composed of ten legs that were connected in series electrically using nickel terminals, and the dimensions of a single leg were 4.0mm×4.0mm×10mm. From evaluations of the measured output characteristics of the modules, it appeared that the electrical resistance of the wiring that is used to connect each leg considerably affects the power output of the unileg module. Thus, we attempted to reduce the wiring resistance of the module and fabricated a module using copper terminals. The observed values of the open-circuit voltage and output power of the Sb-doped Mg2Si unileg module were 496mV and 1211mW at ΔT=531K (hot side: 873K; cool side: 342K).
