The Question of Thermoelectric Devices Electrical Resistance—A Practical Investigation From a Peltier Effect (Thermoelectric Cooler/Thermoelectric Heater) Perspective

Heat Transfer, EarlyView.
ABSTRACT Thermoelectric devices (TEDs) intrinsic electrical resistance is fundamental to its operation. This internal electrical resistance value negatively affects a TED's performance when it is operated as a thermoelectric cooler (TEC), and positively affects a TED when operated as a thermoelectric heater (TEH).

High Power Density for All‐Fe2VAl‐based Thermoelectric Module by Enhancing the Power Factor of p‐type Leg Through Defect‐Engineering and Wetting Effect

Small Methods, EarlyView.
ABSTRACT The high thermoelectric performance of Fe2VAl stems from its sharply rising band edges on either side of the band gap, which is highly sensitive to composition. Addressing reproducibility and scale‐up challenges, we have developed a strategy to enhance its p‐type thermoelectric performance by defects and grain boundary engineering through ...
