“…At present, much attention is paid to the development and study of new highly efficient thermoelectric materials in the scientific world, which can be judged by the greatly increased number of publications in this field in the past decade. Modern strategies for the search and synthesis of promising thermoelectrics are based on the quantum theory of solids and the latest advances in nanotechnology [ 3 , 4 , 82 , 83 ]. Depending on the group of materials (film, bulk, superlattice, supramolecular, etc.)…”

“…Binary copper and silver chalcogenides have excellent thermoelectric characteristics, which continue to be the subjects of intense research [2,4,82,83,109,139,[164][165][166][167]. Over the past 5 years, as examples, we can mention the works [12,14,17,31,39,99,106,129,168,169] on Cu 2-δ S, the works [15,16,165,167,[170][171][172][173][174][175][176][177][178] on Cu 2−δ Se, the works [110,[179][180][181][182][183][184][185] on Cu 2−δ Te, the works [186][187][188][189][190] on Ag 2+δ Se, the works [191][192]…”

This review presents thermoelectric phenomena in copper chalcogenides substituted with sodium and lithium alkali metals. The results for other modern thermoelectric materials are presented for comparison. The results of the study of the crystal structure and phase transitions in the ternary systems Na-Cu-S and Li-Cu-S are presented. The main synthesis methods of nanocrystalline copper chalcogenides and its alloys are presented, as well as electrical, thermodynamic, thermal, and thermoelectric properties and practical application. The features of mixed electron–ionic conductors are discussed. In particular, in semiconductor superionic copper chalcogenides, the presence of a “liquid-like phase” inside a “solid” lattice interferes with the normal propagation of phonons; therefore, superionic copper chalcogenides have low lattice thermal conductivity, and this is a favorable factor for the formation of high thermoelectric efficiency in them.

“…The fabrication methods suitable for large-scale production need to be explored thoroughly in all the concerned aspects. In our previous paper [ 7 ], we have dealt with identifying low-toxic and earth-abundant nanostructured materials in different operating temperatures. Yet, these materials are behind conventional materials and require further enhancement for successful embedment.…”

Thermoelectricity is a promising technology that directly converts heat energy into electricity and finds its use in enormous applications. This technology can be used for waste heat recovery from automobile exhausts and industrial sectors and convert the heat from solar energy, especially in hot and humid areas such as Qatar. The large-scale, cost-effective commercialization of thermoelectric generators requires the processing and fabrication of nanostructured materials with quick, easy, and inexpensive techniques. Moreover, the methods should be replicable and reproducible, along with stability in terms of electrical, thermal, and mechanical properties of the TE material. This report summarizes and compares the up-to-date technologies available for batch production of the earth-abundant and ecofriendly materials along with some notorious works in this domain. We have also evaluated and assessed the pros and cons of each technique and its effect on the properties of the materials. The simplicity, time, and cost of each synthesis technique have also been discussed and compared with the conventional methods.

In the wake of lead-halide perovskite research, bismuth-and antimony-based perovskite-inspired semiconducting materials are attracting increasing attention as safer and potentially more robust alternatives to lead-based archetypes. Of particular interest are the group IB-group VA halide compositions with a generic formula A x B y X x+3y (A + = Cu + /Ag + ; B 3+ = Bi 3+ /Sb 3+ ; X -= I -/Br -), i.e., silver/copper pnictohalides and derivatives thereof. This family of materials forms 3D structures with much higher solar cell efficiencies and greater potential for indoor photovoltaics than the lower-dimensional bismuth/ antimony-based perovskite-inspired semiconductors. Furthermore, silver/ copper pnictohalides are being investigated for applications beyond photovoltaics, e.g., for photodetection, ionization radiation detection, memristors, and chemical sensors. Such versatility parallels the wide range of possible compositions and synthetic routes, which enable various structural, morphological, and optoelectronic properties. This manuscript surveys the growing research on silver/copper pnictohalides, highlighting their composition-structure-property relationships and the status and prospects of the photovoltaic and optoelectronic devices based thereon. The authors hope that the insights provided herein might accelerate the development of eco-friendly and stable perovskiteinspired materials for next-generation photovoltaics and optoelectronics.
