Oxide perovskite materials have a long history of being investigated for thermoelectric applications. Compared to the state-of-the-art tin and lead chalcogenides, these perovskite compounds have advantages of low toxicity, eco-friendliness, and high elemental abundance. However, because of low electrical conductivity and high thermal conductivity, the total thermoelectric performance of oxide perovskites is relatively poor. Variety of methods were used to enhance the TE properties of oxide perovskite materials, such as doping, inducing oxygen vacancy, embedding crystal imperfection, and so on. Recently, hybrid perovskite materials started to draw attention for thermoelectric application. Due to the low thermal conductivity and high Seebeck coefficient feature of hybrid perovskites materials, they can be promising thermoelectric materials and hold the potential for the application of wearable energy generators and cooling devices. This mini-review will build a bridge between oxide perovskites and burgeoning hybrid halide perovskites in the research of thermoelectric properties with an aim to further enhance the relevant performance of perovskite-type materials.
钙钛矿氧化物材料在热电应用方面的研究已有很长历史。与目前最先进的锡和铅硫族化物相比，这些钙钛矿化合物具有低毒性、环保和元素丰度高的优点。然而，由于电导率低和热导率高，钙钛矿氧化物的整体热电性能相对较差。人们采用了多种方法来提高钙钛矿氧化物材料的热电性能，如掺杂、引入氧空位、引入晶体缺陷等。最近，杂化钙钛矿材料开始在热电应用中受到关注。由于杂化钙钛矿材料具有低热导率和高塞贝克系数的特点，它们有望成为热电材料，并在可穿戴能量发生器和冷却装置的应用中具有潜力。本综述将在钙钛矿氧化物和新兴的卤化物杂化钙钛矿之间搭建一座桥梁，以研究热电性能，旨在进一步提高钙钛矿型材料的相关性能。
