PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module which converts heat to electricity at nonconventional high efficiency from the heat source of an intermediate temperature range such as exhaust heat from a dispersion type power supply using a gas turbine, a gas engine or the like, exhaust gas from waste incineration installation, and exhaust gas of cars or the like. SOLUTION: In the thermoelectric conversion module, a p-type thermoelectric element and an n-type thermoelectric element are disposed alternately in a plurality of through-holes provided to a form, and are electrically connected in series by a copper frame spraying electrode. The p-type thermoelectric element consists primarily of zinc and antimony, and is formed of a material having aβtype crystalline structure. The n-type thermoelectric element consists primarily of cobalt and antimony and is formed of a material having a filled skutterudite type structure with a rare earth element filled in a part of the air gap of a crystal. A spraying layer formed of molybdenum or tungsten is between the p-type thermoelectric element and the n-type thermoelectric element, and the copper spraying electrode. COPYRIGHT: (C)2006,JPO&NCIPI |
