## Description

- description: The transverse thermoelectric generation and cooling performances in
    a thermopile module composed of recently developed SmCo5/Bi0.2Sb1.8Te3 artificially
    tilted multilayers are evaluated quantitatively. When a large temperature difference
    of 405°C is applied to the SmCo5/Bi0.2Sb1.8Te3-based module, the open-circuit
    voltage and output power reach 0.51 V and 0.80 W, respectively. The corresponding
    maximum power density is 0.16 W/cm2, even if the power is normalized by the device
    area including areas that do not contribute to the power generation, such as epoxy
    resin, electrodes, and insulating layers. The maximum energy conversion efficiency
    for our module in this condition is experimentally determined to be 0.92%. Under
    the cooling operation, the same module exhibits the maximum temperature difference
    of 9.0°C and heat flow at the cold side of 1.6 W. Although these values are lower
    than the ideal thermoelectric performance expected from the material parameters
    due to the imperfections associated with modularization, the systematic investigations
    reported here clarify a potential of the SmCo5/Bi0.2Sb1.8Te3 artificially tilted
    multilayers as thermoelectric generators and cooling devices.
