“…2,3 Since the first report on ultralow thermal conductivity of CH 3 NH 3 PbI 3 , 4 halide perovskites have been attracting attention as potential thermoelectric materials. 5,6 The thermoelectric conversion efficiency of materials can be measured using a dimensionless figure of merit ZT where S is the Seebeck coefficient, σ is the electrical conductivity, T is the temperature, and κ e and κ L are the electronic thermal conductivity and lattice thermal conductivity, respectively. 7 Lee et al 8 reported ultralow lattice thermal conductivities of all-inorganic halide perovskites CsPbI 3 (yellow polymorph, 0.45 ± 0.05 Wm −1 K −1 ) and CsPbBr 3 (orthorhombic, 0.42 ± 0.04 Wm −1 K −1 ) at room temperature.…”

“…[37][38][39][40] In this critical review, we attempt to address the importance of developing effective doping strategies for MHP thermoelectrics and the resulting impact on charge transport mechanisms. While previous reviews have mainly focused on the general thermoelectric 41,42 and thermal transport properties 43,44 of MHPs, a gap remains in directly addressing electrical doping strategies [45][46][47][48] for MHP thermoelectrics and their resulting impact on charge transport. To fill this gap, we first discuss three types of electrical doping methods implemented in MHPs and recent studies on doping-enhanced thermoelectric performance of MHPs.…”

Over the past decade, metal halide perovskites (MHPs) have received great attention, triggered by the tremendous success of their record‐breaking power conversion efficiency values in solar cells. Recently, there have been significant interests in fully utilizing their unique properties by exploring other device applications including thermoelectrics, which is promising due to their ultralow thermal conductivity and high mobility relative to their competitors among solution‐processable materials. However, the performance of MHP thermoelectrics reported so far falls significantly short of theoretical predictions, as the doping levels achieved to date are typically below the optimum values for maximizing the thermoelectric power factor, indicating the need for effective electrical doping strategies. In this critical review, recent studies aimed at enhancing the thermoelectric properties of MHPs are discussed, with a focus on the relatively under‐explored area of electrical doping in MHPs. The underlying charge transport mechanism and doping effect on transport are also examined. Finally, the challenges facing MHP thermoelectrics are highlighted, and potential research visions for achieving highly efficient thermoelectric conversion based on MHPs are offered.image

“…The second approach involves controlling the κ, which includes both κ e and κ L . The former method employs band engineering to enhance S , while the latter approach optimizes κ L through methods such as nanoscale structures and alloying. , Recently, halide perovskites have garnered more attention because of their exceptional optoelectronic properties, stemming from their large absorption coefficients, high charge carrier mobilities, and large carrier diffusion lengths. In addition, due to the strong lattice anharmonicity and low κ L , the application of perovskites in the field of thermoelectrics has also become a subject of great interest.…”

The performance of thermoelectric (TE) materials is restricted by the coupling between electronic and phonon transport. On the basis of first-principles calculations, self-consistent phonon theory, and the Boltzmann transport equation, this study proposes a novel class of cubic weak-bonding antiperovskites, K 3 IX(Se & Te), which has not been synthesized thus far. These materials exhibit strong lattice anharmonicity and enable the separation of electronic and phonon transport at the atomic level. With quartic anharmonicity correction, antiperovskites K 3 I(Se & Te) are predicted to exhibit remarkably low lattice thermal conductivities κ L . At room temperature, the calculated κ L values of K 3 ISe and K 3 ITe are only 0.60 and 0.18 W m −1 K −1 , respectively. Additionally, these types of materials demonstrate an anomalously weak temperature dependence of κ L , approximately conforming to a power-law relationship where κ L ∼ T −0.3 for K 3 ITe. Simultaneously, the high degeneracy and nearly flat band structure endow K 3 IX(Se & Te) with large power factors when doped. At 800 K, under p-type doping, the calculated ZT values of K 3 ISe and K 3 ITe can reach 1.33 and 2.61, respectively, surpassing those of the leading traditional TE materials. The results have revealed that K 3 IX(Se & Te) represent a promising class of TE materials exhibiting excellent performance, and the structural features that effectively decouple phonon and electron transport also offer novel perspectives for the investigation of highperformance TE materials.
