Abstract

The invention discloses a preparation method of a thin-film thermoelectric material. The preparation method comprises the following steps: preparing a porous alumina template by adopting an electrochemical method; taking the porous alumina template as a working electrode; putting the working electrode and an auxiliary electrode in an electrolyte, and preparing a sample through an electrochemical deposition method, wherein the electrolyte comprises a precursor, a complexing agent and an additive, and the precursor is a combination of two or three of tellurium dioxide, bismuth nitrate and diantimony trioxide; and subjecting the sample to cleaning, drying and annealing treatment in sequence, so as to obtain the thin-film thermoelectric material. The preparation method disclosed by the invention has the advantages that the thin-film thermoelectric material is low in heat conductivity coefficient, high in electrical conductivity, high in Seebeck coefficient and high in thermoelectric figureof merit.

Description

technical field

[0001] The invention relates to the field of new energy materials and preparation methods thereof, in particular to a preparation method of thin-film thermoelectric materials. Background technique

[0002] With the advent of the energy crisis, people began to be aware of the limited and gradual depletion of natural resources, and stimulated commercial interest in the development of new energy and comprehensive utilization of various energy sources. Thermoelectric materials are the most suitable for utilizing temperature differences existing in nature and industrial A new type of energy material that utilizes waste heat and waste heat from automobile exhaust. Thermoelectric material is a functional material that converts heat energy and electric energy. After the current is applied to both ends of the thermoelectric material, it will generate cold and hot ends, which can be used for cooling and heat preservation; the two ends of the thermoelectric material are...
