Peltier components, also known as thermoelectric modules, are solid-state devices that convert electrical energy into temperature differences. They are based on the Peltier effect, discovered by French physicist Jean Charles Athanase Peltier in 1834. The Peltier effect describes the phenomenon where an electric current flowing through a junction of two different conductors produces a temperature difference between the two sides of the junction.

Peltier components consist of multiple thermocouples, which are pairs of p-type and n-type semiconductors. When a voltage is applied across the thermocouples, one side of the component becomes hot while the other side becomes cold. This temperature difference can be used for cooling, heating, or both, depending on the direction of the electric current.

These components are widely used in various applications, including refrigeration, temperature control, and energy harvesting. They are particularly useful in situations where traditional cooling methods are impractical or inefficient. For example, Peltier components are used in portable coolers, medical devices, and even in some automotive applications for seat heating.

One of the main advantages of Peltier components is their solid-state nature, which eliminates the need for moving parts and reduces the risk of mechanical failure. However, they also have some limitations, such as lower efficiency compared to traditional refrigeration methods and the generation of waste heat on the hot side. Despite these limitations, Peltier components continue to be an important technology in modern electronics and engineering.
