What type of effect is the Peltier Seebeck effect?

The Peltier-Seebeck effect involves the conversion of thermal energy into electrical energy and vice versa. This effect is a thermoelectric phenomenon where a temperature difference created across a conductor or semiconductor leads to the generation of a voltage (Seebeck effect) or, when an electrical current is passed through the material, it can create a temperature difference (Peltier effect).

This means that the Peltier-Seebeck effect is fundamentally about the conversion of energy types—thermal energy being converted to electrical energy in the case of the Seebeck effect and electrical energy into thermal energy in the case of the Peltier effect. Therefore, identifying it as an electric conversion process is entirely accurate, as it directly involves the conversion of heat into electricity and highlights the relationship between thermal and electrical energy in materials.
