摘　　要：硫系和卤化物钙钛矿材料具有优良的热电输运性能,以及易制备、稳定性良好等诸多优点,因而受到了广泛关注。筛选具有热电潜力的钙钛矿材料和提升现有钙钛矿材料的热电性能是目前研究的重点内容。本文回顾了钙钛矿和热电材料的基本理论,描述了材料热电性能的表征参数,综述了具有优良热电潜力的钙钛矿材料的研究进展,包括无机硫系和卤化物钙钛矿材料、有机复合钙钛矿材料以及氧化物钙钛矿材料等,并从电子结构、电输运性质、热输运性质以及热电性能调控方法等方面分析了钙钛矿材料具有优异热电优值和优良热电潜力的原因,展望了钙钛矿材料的热电应用前景。In the face of the increasingly severe energy challenges,perovskite materials have received extensive attention in the fields of optoelectronics and thermoelectrics due to their easy synthesis and stability as energy conversion substances.Several theoretical and experimental studies have shown that the outstanding thermoelectric potential inherent in diverse organic and inorganic perovskite materials.It is noteworthy for its exceptional performance in terms of both electrical and thermal conductivity.To promote the application of perovskite materials in the field of thermoelectrics,the current research emphasizes on finding perovskite materials with thermoelectric potential and enhancing the thermoelectric performance of existing materials.First,this paper reviews the fundamental theories of perovskite and thermoelectric materials,describes the characterization parameters of material thermoelectric performance,and then elaborates on the research progress of perovskite materials with excellent thermoelectric potential,including inorganic chalcogenide and halide perovskite materials,organic composite perovskite materials,and oxide perovskite materials.Among them,inorganic chalcogenide and halide perovskite materials have been found to have extremely high thermoelectric figures of merit,comparable to or even better than well-known thermoelectric materials in terms of Seebeck coefficient,power factor,electron thermal conductivity,and lattice thermal conductivity.For example,various chalcogenide perovskite materials such as CaZrS_(3),CaZrSe_(3),and BaZrS_(3),as well as various halide perovskite materials such as Rb_(2)SnI_(6),CsPbBr_(3),and CsSnI_(3),exhibit large Seebeck coefficient and ultra-low lattice thermal conductivity.Their thermoelectric figures of merit can reach around 1 or even exceed 4 for CaZrS_(3) at high temperatures,indicating that perovskite materials have the potential to become a new choice for thermoelectric applications.Simultaneously,at the same time,the anisotropic property has been observed cl
