The working principle of the invention is as follows:
when two kinds of metal conductors or semiconductors having different free electron densities or carrier densities in a temperature difference environment are in contact with each other, electrons on a contact surface diffuse from a high concentration to a low concentration, and the diffusion rate of the electrons is proportional to the temperature difference of the contact region. Therefore, as long as the temperature difference between the two contacting conductors is maintained, electrons can continue to diffuse, and a stable voltage is formed between the other two terminals of the two conductors, which is called the seebeck effect. Thermoelectric power generation is to utilize the seebeck effect to form seebeck voltage by maintaining a temperature difference between two ends of a thermoelectric unit, thereby generating electric power output.
