How the thermoelectric effect can be used for energy conversion?

The thermoelectric effect can be utilized for energy conversion through the Seebeck effect, where a temperature gradient across a thermoelectric material generates a voltage, enabling the conversion of heat energy into electrical energy. This principle is applied in thermoelectric generators (TEGs), which can harness waste heat from industrial processes or automotive engines. Conversely, the Peltier effect allows for cooling applications by applying an electrical voltage to create a temperature difference. Overall, thermoelectric materials provide a means to efficiently convert thermal energy into usable electrical energy and vice versa.
