## Description

- description: In this study, we propose an accurate, simple, and versatile measurement
    method for power generation efficiency and device figure of merit ZT of thermoelectric
    devices. Toward the energy harvesting applications of thermoelectric generators,
    the performance characterization under low heat inflow and temperature difference
    is crucial. However, when the conventional solid-state heat flow meter is used,
    the uncertainty of power generation performance increases as heat input decreases.
    We have solved these problems by using a laser for heat input, improving the simplicity
    and accuracy of power generation efficiency measurements, especially at low heat
    flow. The direct and non-contact measurement of the temperature difference by
    using a thermography allowed us to determine ZT as well as power generation efficiency.
    The obtained mean power generation efficiency and ZT values are consistent with
    the values obtained by the conventional method within the error range, thereby
    validating the reliability of the proposed method. The relative uncertainties
    of the efficiency and ZT were estimated to be less than 3% and 12% for our method,
    respectively, whereas those were 19% and 24% in situations where the temperature
    difference was less than 6 K for the conventional method.
