1. A method for preparing a thermoelectric thick film, comprising:
determining a brittle-to-ductile transition temperature of a blocky thermoelectric material;
rolling the blocky thermoelectric material within a temperature range above the brittle-to-ductile transition temperature and below a melting point, parameters of the rolling including a linear speed of rollers being 0.01 mm/s to 10 mm/s, and an amount of pressing each time of the rollers being controlled at 0.0005 mm to 0.1 mm;
repeating the rolling of the blocky thermoelectric material to form the thermoelectric thick film with a specified thickness; and
annealing the thermoelectric thick film with the specified thickness, a temperature of the annealing being 100° C. to 800° C., and a duration of the annealing being 10 to 500 hours.
