ELECTRICITY GENERATION METHOD USING THERMOELECTRIC GENERATION ELEMENT, THERMOELECTRIC GENERATION ELEMENT AND MANUFACTURING METHOD THEREOF, AND THERMOELECTRIC GENERATION DEVICE

摘要

A thermoelectric generation element comprises a stack which is sandwiched by, and electrically connected to, a first electrode and a second electrode which are positioned facing one another, said stack having a structure wherein Bi2Te3 layers are stacked alternately with metallic layers containing either Ni or Co. The ratio of the thickness of the metallic layers to the thickness of the Bi2Te3 layers is in the range of metallic layer : Bi2Te3 layer = 20 : 1 - 0.5 : 1. The stack faces of the Bi2Te3 layers and the metallic layers are inclined at an angle of inclination ? which is 10-60 degrees from the direction in which the first electrode and the second electrode face one another. A potential difference arises between the first and second electrodes from a temperature difference in the perpendicular direction. Thus is provided a thermoelectric generation element, and an electricity generation method and thermoelectric generation device using the element.
