Solid-state thermoelectrics can convert waste heat to electrical energy, but applications are hindered by long-term stability issues. Here cobalt is used as a contact layer with direct bonding to thermoelectric MgAgSb, enabling a thermoelectric module to achieve 10.2% conversion efficiency over 1,440 h of thermal cycling.
