Effect of transport in a semiconductor thermoelectric generator on its efficiency

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The effects of electrical transport and thermal diffusion in the working medium of a thermoelectric generator (TEG) on its efficiency and maximum useful power are examined. Equations are derived to describe these effects, and dimensionless parameters are found whose values are governed by the thermodynamic and kinetic characteristics of the material. Numerical estimates carried out show that it is possible to increase the efficiency and power of a TEG by selecting materials having suitable transport characteristics. The semiconductor alloys of the T1-S system are interesting in this regard.
