Abstract
We provide the rationale for possible significant improving efficiency of low-temperature thermoelectric generators (TEGs) based on bismuth-antimony telluride (Bi2Te3)x(Sb2Te3)1−x ternary alloys.
It has been shown by experiments that using in TEGs of p-type legs made of (Bi2Te3)x(Sb2Te3)1−x material with orientation alternative to traditional, i.e., when cleavage planes of legs are transverse to heat flux direction, results in increasing in thermoelectric efficiency by an average of 25% in the temperature range from 100 °C to 350 °C.
