“…Other metal cations such as bismuth (Bi) and copper (Cu) have successfully formed perovskites in the form of (MA) 3 Bi 2 I 9 , Cs 3 Bi 2 I 9 , and (MA) 2 CuCl 2 Br 2 as non‐toxic alternatives. [ 57–59 ] Recently, many double perovskites based on mixing different metal cations into a single perovskite structure were reported with enhanced stability. [ 60 ] Notwithstanding, their inferior light absorption, wide bandgap, and difficulty in processing have limited the use of non Pb‐ and Sn‐based perovskites.…”

The recent re-emergence of halide perovskites has received escalating interest for optoelectronic applications. In addition to photovoltaics, the multifunctional nature of halide perovskites has led to diverse applications. The ultralow thermal conductivity coupled with decent mobility and charge carrier tunability led to the prediction of halide perovskites as a possible contender for future thermoelectrics. Herein, recent advances in thermal transport of halide perovskites and their potentials and challenges for thermoelectrics are reviewed. An overview of the phonon behavior in halide perovskites, as well as the compositional dependency is analyzed. Understanding thermal transport and knowing the thermal conductivity value is crucial for creating effective heat dissipation schemes and determining other thermal-related properties like thermo-optic coefficients, hot-carrier cooling, and thermoelectric efficiency. Recent works on halide perovskite-based thermoelectrics together with theoretical predictions for their future viability are highlighted. Also, progress on modulating halide perovskite-based thermoelectric properties using light and chemical doping is discussed. Finally, strategies to overcome the limiting factors in halide perovskite thermoelectrics and their prospects are emphasized.

“…Mechanochemical synthesis (MCS) has recently emerged as a very convenient and reliable method to obtain high quality LHPs as well as other lead-free multinary metal halides. 4,5,[14][15][16][17][18][19][20][21][22][23][6][7][8][9][10][11][12][13] Bulk materials have been obtained with a variety of compositions including fully-inorganic as well as hybrid organic-inorganic perovskites. MCS has been used to investigate the role of additives and dopants introduced in wellcontrolled small amounts.…”

“…4,21,24,25 Colloidal quantum dots with photoluminescence quantum yields over 80% have also been produced by MCS. 9,17,20,24,26 Eventually, ternary nonperovskite metal halides such as guanidinium-based 2D and 1D structures 19 or bismuth-based 2D and 0D crystals 22 have also been produced and shown to possess promising optoelectronic properties by MCS. It is also worth noting that materials prepared by MCS can be turned into thin films by solution-or vacuum-deposition techniques, thus enabling their use in common thin-film-based devices (e.g., solar cells or LEDs).…”

Halide perovskites have undergone an impressive development and could be used in a wide range of optoelectronic devices, where some of them are already at the edge of commercialization, e.g., perovskite solar cells. Recently, interest in perovskites in powder form has increased, as for example, they are found to exhibit high stability and allow for easy production of large quantities. Accordingly, also the topic of processing thin and thick films on the basis of perovskite powders is currently gaining momentum. Here, perovskite powder can form the basis for both, typical wet and solvent-based processing approaches, as well as for dry processes. In this Progress Report, the recent developments of halide perovskites in powder form and of film processing approaches are summarized that are based on them. The advantages and opportunities of the different processing methods are highlighted, but their individual drawbacks and limitations are also discussed. Prospects are also pointed out and possible steps necessary to unlock the full potential of powder-based processing methods for producing high quality thick and thin perovskite layers in the future are discussed.
