Thermoelectric materials are attracting considerable attention to alleviate the global energy crisis by enabling the direct conversion of heat into electricity. As a class of I-V-VI semiconductors, AgBiSe is expected to be the potential thermoelectric material to replace conventional PbTe-based compounds due to its non-toxic and abundant nature of its constituent elements. This review article summarizes the fundamental properties of AgBiSe, thermoelectric properties, the effect of different dopants on its transport properties and entropy engineering for cubic phase stabilization with the detailed description of related techniques used to analyze the properties of AgBiSe. The current thermoelectric figure-of-merit and approaches to further improve performance and operational stability are also discussed.
热电材料通过实现将热能直接转化为电能，在缓解全球能源危机方面正吸引着相当多的关注。作为一类I-V-VI族半导体，AgBiSe有望成为潜在的热电材料，以取代传统的基于PbTe的化合物，因为其组成元素具有无毒且储量丰富的特性。这篇综述文章总结了AgBiSe的基本性质、热电性质、不同掺杂剂对其输运性质的影响以及用于立方相稳定化的熵工程，并详细描述了用于分析AgBiSe性质的相关技术。还讨论了当前的热电优值以及进一步提高性能和运行稳定性的方法。
