热电材料通过将热能转化为电能，为解决能源问题提供了关键的解决方案。我们报道了配合物Zintl化合物Yb14MnSb11打破了20年来高温（bbb900 K） p型热电发电材料开发的停滞。这种材料的效率是目前最先进的SiGe的四倍，优点几乎翻了一番，因此在分段设备中的热电应用中具有优势。Yb14MnSb11代表了第一个具有比任何其他竞争材料更高的优点和效率的复杂Zintl相，开辟了一类具有显着化学和物理性能的新型热电化合物。
Thermoelectric materials provide a key solution to energy problems through the conversion of heat into electrical energy. We report that the complex Zintl compound, Yb14MnSb11, breaks a 2-decade stagnation in high-temperature (> 900 K), p-type materials development for thermoelectric power generation. This material achieves quadrupled efficiency and virtually doubled figure of merit over the current state-of-the-art, SiGe, thus earmarking it superior for thermoelectric applications in segmented devices. Yb14MnSb11 represents the first complex Zintl phase with substantially higher figure of merit and efficiency than any other competing materials, opening a new class of thermoelectric compounds with remarkable chemical and physical properties.
