Heading H1K [Also in Division B3] The connections between adjacent elements of a thermoelectric module consisting of an array of bismuth telluride based semi-conductor bodies are made by an alloying technique in which gold or silver members are applied to the ends of a pair of such bodies under pressure at a temperature below the melting point of either the metal or the semi-conductor. The pairs of a complete module may be inter-oonnected sequentially or simultaneously, preferably by use of a heated presser foot, Fig. 2 (not shown). Preferred materials for the semi-conductor are Bi 2 Te 3 , Bi 2 Te 3 with Bi 2 Se 3 , or Bi 2 Te 3 with Sb 2 Te 3 . In forming a module of which the elements are encased in insulant, the insulant may be undercut around the edges of the semi-conductor body ends to be contacted so that molten insulant does not contaminate the alloy bond.
