## Description

- description: Thermoelectric (TE) technology enables direct heat-to-electricity conversion
    and is gaining attention as a clean, fuel-saving, and carbon-neutral solution
    for industrial, automotive, and marine applications. Despite nearly a century
    of research, apart from successes in deep-space power sources and solid-state
    cooling modules, the industrialization and commercialization of TE power generation
    remain limited. Since the new millennium, nanostructured bulk materials have accelerated
    the discovery of new TE systems. However, due to limited access to high-temperature
    heat sources, energy harvesting still relies almost exclusively on BiTe-based
    alloys, which are the only system operating stably near room temperature. Although
    many BiTe-based compositions have been proposed, concerns over reproducibility,
    reliability, and lifetime continue to hinder industrial adoption. Here, we aim
    to develop reference BiTe-based thermoelectric materials through data-driven analysis
    of Starrydata2, the world’s largest thermoelectric database. We identify Bi0.46Sb1.54Te3
    and Bi2Te2.7Se0.3 as the most frequently studied ternary compositions. These were
    synthesized using hot pressing and spark-plasma sintering. Thermoelectric properties
    were evaluated with respect to the processing method and measurement direction.
    The results align closely with the median of reported data, confirming the representativeness
    of the selected compositions. We propose these as reference BiTe materials, accompanied
    by transparent data and validated benchmarks. Their use can support the standardization
    of TE legs and modules while accelerating performance evaluation and industrial
    integration. We further estimated the performance of a thermoelectric module made
    from the reference composition, which gives the power output of over 2.51 W and
    an efficiency of 3.58% at a temperature difference of 120 K.
