Abstract

In the paper, the influence factors of conversion efficiency are analyzed. Firstly, the thermoelectric unit is simulated in three dimensions, the temperature field and potential field are analyzed, and the influence factors of thermoelectric efficiency are considered. The output power of the thermoelectric unit is basically consistent with the increasing temperature difference, and the greater the temperature difference is, the greater the output power changes; With the increase of solar irradiance, the temperature at hot end increases rapidly; The cold end temperature increases slowly; Due to the increase of temperature difference, the conversion efficiency increases at a high speed and then gradually slows down; Under different temperature differences, the output power increases to a certain peak value with the load resistance, and then gradually decreases with the load resistance.
