Abstract:
A thermoelectric module for converting thermal energy to electrical energy comprising:a P-type thermoelectric material prepared from a complex oxide having the formula: (A0.4B0.1M0.1)x/0.6Co2Oy wherein A and B are elements differing from each other, A and B represent Ca, Sr or Ba, M represents Bi, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb or Lu, 1.7&lE;x&lE;2, and 3.8&lE;y&lE;5; wherein the complex oxide has a Seebeck coefficient of 100 &mgr;V/K or more at a temperature of 100 K (absolute temperature) or higher, and wherein the complex oxide has an electrical resistivity of 10 m&OHgr;cm or less at a temperature of 100 K (absolute temperature) or higher; a N-type thermoelectric material; at least one electrode joining said P-type thermoelectric material to said N-type thermoelectric material; and a wire connected to said P-type thermoelectric material; and a wire connected to said N-type thermoelectric material.
