Thermoelectric generators (TEG) are one way to utilize the cold energy of LNG. Inadequate research on the Seebeck coefficient (α) of thermoelectric materials at cryogenic temperatures has hindered the design of TEG at cryogenic temperatures. Consequently
this paper proposes a method to measure α of the thermoelectric material
Bi2Te3
at cryogenic temperatures using a TEG module experiment
which measures α of thermoelectric materials in the temperature range of 90 K to 180 K. The results showed that α of Bi2Te3 decreased with decreasing temperature. When the temperature decreased from 180 K to 90 K
