Construction of a thermoelectric module

   A thermoelectric module consists of a number of alternate p- and n- type semiconductor thermoelements, which are connected electrically in series by metal interconnects, sandwiched between two electrically insulating and thermally conducting ceramic substrates. Alloys of the Bismuth Telluride or the Bismuth Selenide and the Antimony use for making of semiconductor elements. Lead wires joint to the ceramic substrate that is called “hot side”, other ceramic substrate is called “cold side”.
