PeltierSeebeck

PeltierSeebeck refers to the combined thermoelectric effects discovered by Jean Charles Athanase Peltier and Thomas Johann Seebeck. These phenomena are related to the conversion of temperature differences into electrical voltage and vice versa.

The Seebeck effect, discovered by Thomas Johann Seebeck in 1821, describes how a temperature gradient in a conducting material can generate an electromotive force (voltage). When two dissimilar conductors are joined at two junctions and these junctions are maintained at different temperatures, a current will flow. This effect is the basis for thermoelectric generators, which convert heat directly into electricity.

The Peltier effect, observed by Jean Charles Athanase Peltier in 1834, is the inverse of the Seebeck effect. It states that when an electric current flows through a junction of two dissimilar conductors, heat is either absorbed or released at that junction. If the current flows in one direction, heat is absorbed, causing cooling. If the current is reversed, heat is released, causing heating. This effect is utilized in thermoelectric coolers, often found in small refrigerators or cooling devices.

Together, the Peltier and Seebeck effects demonstrate the direct interconversion of thermal and electrical energy in certain materials. This thermoelectricity finds applications in niche areas where conventional methods of heating or cooling are impractical or where waste heat can be efficiently converted into usable electricity. Research continues to improve the efficiency of thermoelectric materials for broader applications.
