Comparison of Two Different Peltiers Running as Thermoelectric Generator at Different Temperatures

Nowadays the peltier is used to cool the small device cooler when we apply DC voltage to its terminals. Instead of applying a DC voltage to the terminals, the peltier runs as a thermoelectric generator and we get DC voltages at its terminals, which we create a temperature difference between the two surfaces of the ceramic. In this way, electricity can be obtained directly from the heat flow by utilizing the waste heat of the resources we use (thermal water, car exhaust, boiler heat, solar energy etc.) that are stored around. In this study, copper material with high conduction of heat is preferred and two different thermoelectric modules are placed between the two plates which we traverse hot and cold water. These thermoelectric modules run as thermoelectric generators to compare current, voltage and power generation with different temperature.
