Peltier Effect Discovery History 1834 The Story Behind the Find
Limitations and Material Considerations Despite its advantages, the efficiency of a Peltier module is currently lower than that of conventional refrigeration methods. Unlike the Seebeck effect, which converts temperature differences directly into electrical voltage, the Peltier effect consumes electrical energy to create a temperature differential.
The performance heavily depends on the quality of the semiconductor materials used, typically bismuth telluride for room-temperature applications. The Peltier effect describes the phenomenon where heat energy is absorbed or released at the junction of two different conductors or semiconductors when an electric current passes through them.

This energy transfer manifests as a change in temperature, with one junction acting as a heat sink and the other as a heat source. When a current is applied, these charge carriers gain or lose kinetic energy depending on the direction of the flow and the specific materials used.
