N-type lead selenide thermoelectric material, thermoelectric refrigeration device and preparation method
The invention discloses an n-type lead selenide thermoelectric material, a thermoelectric refrigeration device and a preparation method. The chemical formula of the n-type lead selenide thermoelectric material is Pb < 1-x > (GaSb) < x > Se < 1-y >, xlt; 0.002, 0 lt, 0.002, 0 lt; and y < = 0.007. The room temperature thermoelectric figure of merit of the prepared Pb < 0.99875 > (GaSb) < 0.00125 > Se < 0.999 > material is about 0.6. When the temperature of the hot end of the thermoelectric refrigeration device made of the n-type Pb0. 99875 (GaSb) 0.00125 Se0. 999 material and the temperature of the hot end of the thermoelectric refrigeration device made of the p-type bismuth telluride material are 300K, 323K and 343K respectively, the obtained maximum refrigeration temperature differences are 38K, 46K and 56K respectively.
