Mg 3 (Sb, Bi) 2 -based compounds have recently attracted intense attention as thermoelectric (TE) materials for power generation and cooling applications because of their high TE performance. The contact interface layers play a crucial role in achieving a high conversion efficiency of TE devices. Iron contacts have often been used for the Mg 3 (Sb, Bi) 2 compound; however, a large drawback for device fabrication is their incompatibility with solder. In this study, we developed cupronickel as a potential interface contact layer for Mg 3 (Sb, Bi) 2 . A crack-free interface with a low specific contact resistance of ∼5 μΩ cm 2 enables a maximum conversion efficiency (η max ) of ∼8% for the singleleg cupronickel/Mg 3 (Sb, Bi) 2 /cupronickel. Additionally, a η max of ∼7.8% is realized for a 2-pair module of Mg 3 (Sb, Bi) 2 and MgAgSb at a temperature difference (ΔT) of 277 K. The optimization of the cupronickel contact layer in this study has the potential to enhance the conversion efficiency of Mg 3 (Sb, Bi) 2 -based compounds.
