Abstract	Cu2Se/Mo/Cu2Se thermoelectric joints were fabricated by the one-step hot pressing method using Mo as the barrier layer for Cu2Se. It is found that the Cu2Se/Mo interface has ultralow electrical contact resistivity but poor (t)ensile strength. Via introducing 5% (mass fraction) Mn in Mo, the tensile strength is improved by three times while still maintaining low electrical contact resistivity, which are attributed to the diffusion of Mn in Cu2Se during the hot pressing process. The evolutions of microstructure and contact resistivity at the interface during long-term aging at high temperatures (650 and 800 degrees C) were investigated. After aging experiments, the interface remains integrity with low contact resistivity, which proves that the Mo-Mn mixed phase is a promising candidate as the barrier layer for Cu2Se-based thermoelectric generators.
