In this paper we report the use of high temperature solder alloys that allow the fabrication of high temperature thermoelectric modules. As an initial approach, well-known Bi2Te3 thermocouples were fabricated using a 301 °C melting point solder alloy. Secondly, junctions of promising thermoelectric materials for high temperatures were prepared employing a 715 °C solder. The properties of the junctions are evaluated and the experimental procedure to obtain the contacts is described, providing a methodology for the fabrication of high-temperature thermoelectric modules.
