The Seebeck effect is a phenomenon where a voltage is generated across two dissimilar conductors or semiconductors when there is a temperature difference between them. This effect is the basis for thermoelectric generators, which convert heat directly into electrical energy, and is crucial in temperature sensing applications like thermocouples.

dissimilar conductors

Semiconductors are materials with electrical conductivity between that of a conductor and an insulator, crucial for modern electronics. They are the foundation of integrated circuits and devices like transistors, enabling the miniaturization and performance enhancement of electronic technologies.

semiconductors

Temperature difference refers to the variation in thermal energy between two points, which can drive heat transfer from the warmer to the cooler area. This principle is fundamental in thermodynamics, influencing processes such as conduction, convection, and radiation, and is crucial in applications ranging from weather systems to industrial heat exchangers.

temperature difference

Thermoelectric generators convert heat directly into electricity using the Seebeck effect, which occurs when a temperature difference across a material generates an electric voltage. These devices are valued for their ability to harvest waste heat from various sources, enhancing energy efficiency and offering a sustainable power solution in remote or off-grid locations.
