In addition to the broadly anticipated use of metal halide perovskites in photovoltaics and light-emitting devices, they also hold a great promise as cost-effective thermoelectrics, as they may offer an ultra-low thermal conductivity combined with a high Seebeck coefficient. This Review summarizes the recent advances in theoretical analysis and experimental studies of the thermoelectric properties of these materials, with a particular focus on organic–inorganic (hybrid) halide perovskites and low-dimensional analogues. After a short introduction of figures of merits of thermoelectric materials, we consider measurement methods used to characterize thermoelectric materials and outline some difficulties in applying those methods to perovskites, since accurate measurements are essential for further progress of this emerging research area. We then outline in detail the current progress achieved in metal halide perovskite thermoelectrics and offer a detailed discussion of possible strategies to resolve the discrepancy between their high theoretically predicted ZT values (1–2 at room temperature) and still rather low (below 0.2) experimental values.

金属卤化物钙钛矿作为新兴热电材料

除了广泛预期在光伏和发光器件中使用金属卤化物钙钛矿外，它们作为具有成本效益的热电材料也具有很大的前景，因为它们可以提供超低的热导率和高的塞贝克系数。本综述总结了这些材料热电特性的理论分析和实验研究的最新进展，特别关注有机-无机（杂化）卤化物钙钛矿和低维类似物。在简要介绍了热电材料的品质因数之后，我们考虑了用于表征热电材料的测量方法，并概述了将这些方法应用于钙钛矿的一些困难，因为准确的测量对于这一新兴研究领域的进一步发展至关重要。ZT值（室温下为 1–2）和仍然相当低（低于 0.2）的实验值。
