Thermoelectric Modules Incorporating MgAgSb and Mg ₃ (Sb,Bi) ₂ Synthesized Using a Melting Method

Thermoelectric Modules In their Research Article (10.1002/adem.202502649), Chul-Ho Lee and co-workers fabricate a thermoelectric power module of MgAgSb/Mg3(Sb,Bi)2 with an air-cooled heat exchanger. Lower thermal conductivity leads to a larger temperature difference than that with the Bi2Te3 module, resulting in comparable electrical power generation. This result demonstrates that the present module is a promising alternative to the conventional Bi2Te3 module that has been the best performing thermoelectric module near room temperature for over a half century.
