Thermoelectric Efficiency of Bi-Sb and Bi-Se Based Thermoelements

Abstract

The article discusses the properties of solid solutions based on bismuth and antimony, which are considered the best thermoelectric materials for the low temperature range. The improvement of the conversion efficiency in thermoelectric materials is primarily due to the increase in the efficiency coefficient (Z), which can be achieved by forming solid solutions of semiconductor materials. Graphs related to thermoelectric power, electrical conductivity, and mobility of charge carriers in the alloy are presented.
