Theoretical basis of thermoelectric power generation
According to Seebeck effect, open circuit (no load) voltage U=a (Th Tc)=a* ΔТ Formula ①
Considering load, output voltage=a* ΔТ* RL/(Ri+RL)  Formula ②
Current in the circuit I=U/(Ri+RL)=a* ΔТ/ (Ri+RL)  Formula ③
When no load RL=0, it is called an open circuit, and the open circuit current I=a* ΔТ/ Ri  type ④
From P=UI, output power=a* ΔТ* RL/(Ri+RL) *a* ΔТ/ (Ri+RL)
That is, P=a 2* ΔТ 2 * RL/(Ri+RL) 2  Formula ⑤
When Ri=RL, P=Pmax=a 2* ΔТ 2/(4Ri)  Type ⑥
According to formulas ⑤ and ⑥, the output power is proportional to the square of the temperature difference.
The maximum output power is inversely proportional to the internal resistance of the device.
According to formula ②, the larger the load resistance is, the greater the output voltage will be.
Application Considerations
● The generator module must be installed on a flat surface, and the flatness of the contact surface is required to be more than 30 microns.
● The pressing force must be no less than 1215 KG/CM2.
● The temperature of hot surface shall not exceed 200 ℃.
