“…The introduction of appropriate inclusions in polycrystalline SnSe can achieve a high peak ZT in SnSe system [84,276]. Many different types of inclusion, such as second phase (SnSe 2 [84] and Se nanowires [297]), nanoprecipitates (rock-salt-type SnSe [141] and Sn oxides [67]), simple substance (carbon black nanoinclusions [298]), compounds (SnS [129,299], 2D-MoSe 2 [300]) and compounds (SiC [259] and PbTe [301] SnS [257]. SnSe can also be treated as inclusion in other thermoelectric materials systems, such as (Cu 2 Se) 0.97 (SnSe) 0.03 [303], and (PbSe) 0.9 (SnSe) 0.1 [257].…”

Thermoelectric materials offer an alternative opportunity to tackle the energy crisis and environmental problems by enabling the direct solid-state energy conversion. As a promising candidate with full potentials for the next generation thermoelectrics, tin selenide (SnSe) and its associated thermoelectric materials have been attracted extensive attentions due to their ultralow thermal conductivity and high electrical transport performance (power factor). To provide a thorough overview of recent advances in SnSe-based thermoelectric materials that have been revealed as promising thermoelectric materials since 2014, here, we first focus on the inherent relationship between the structural characteristics and the supreme thermoelectric performance of SnSe, including the thermodynamics, crystal structures, and electronic structures. The effects of phonon scattering, pressure or strain, and oxidation behavior on the thermoelectric performance of SnSe are discussed in detail. Besides, we summarize the current theoretical calculations to predict and understand the thermoelectric performance of SnSe, and provide a comprehensive summary on the current synthesis, characterization, and thermoelectric performance of both SnSe crystals and polycrystals, and their associated materials. In the end, we point out the controversies, challenges and strategies toward future enhancements of the SnSe thermoelectric materials.

“…Similarly, a very low lattice thermal conductivity of SnSe makes a good zT of 1.1 at 773 K . Textured SnSe polycrystals with a good thermoelectric behavior were reported by Li et al Similarly, a high thermoelectric zT of 1.21 at 903 K has been realized in SnSe by incorporation of a proper fraction of carbon black as nanoinclusions …”

The depletion of nonrenewable energy sources insisted the search for new types of energy solutions. Thermoelectric conversion is one possible energy solution which converts waste heat into useful electricity. In the past several years, thermoelectric research developed many novel materials. Among these, most of the practically useful materials with better performance are based on Bi, Pb, Te, and Sb, but are toxic and expensive. There is a need of earth‐abundant, low‐cost, and less‐toxic compounds with superior thermoelectric performance so as to realize the large‐scale commercial applications. Recent studies have identified eco‐friendly thermoelectric materials based on the alloys of copper and sulfur, suggesting an alternative to the well‐established expensive thermoelectric materials. These compounds exhibit interesting electronic properties with better thermoelectric efficiency (zT). The structural properties permit to decouple electrical and thermal conductivities, which is an essential requirement to get improved efficiency. Several approaches, such as phase tuning, doping, nanostructure/microstructure designing, compound formation, etc., are chosen to increase the performance. On the whole, the present review summarizes the strategies and techniques that have been adopted to improve the thermoelectric behavior of copper sulfides and its compounds.

“…Although the presence of the grain boundaries and MWCNT/(Bi 0.2 Sb 0.8 ) 2 Te 3 interfaces resulted in extra scattering of the carriers and hence reduced electrical conductivity, the overall improvement is attributed mainly to the reduction of thermal conductivity as a result of strong phonon scattering. Li et al [178] reported a high figure of merit of 1.21 for polycrystalline p-type SnSe when incorpo- rated with 2.5 vol% of carbon black. The improvement is attributed mainly to the increase in electrical conductivity resulting in a high power factor.…”

Thermoelectric materials have long been proven to be effective in converting heat energy into electricity and vice versa. Since semiconductors have been used in the thermoelectric field, much work has been done to improve their efficiency. The interrelation between their thermoelectric physical parameters (Seebeck coefficient, electrical conductivity, and thermal conductivity) required special tailoring in order to get the maximum improvement in their performance. Various approaches have been reported in the research for developing thermoelectric performance, including doping and alloying, nanostructuring, and nanocompositing. Among different types of thermoelectric materials, layered chalcogenide materials are unique materials with distinctive properties. They have low self-thermal conductivity, and their layered structure allows them to be modified easily to improve their thermoelectric performance. In this review, basic knowledge of thermoelectric concepts and challenges for enhancing the figure of merit is provided. It discusses briefly different groups of layered chalcogenide thermoelectric materials with their structure and thermoelectric properties. It also reports different approaches in the literature for improving their performance and the recent progress done in this field. It highlights graphene as a promising nano additive to layered chalcogenide materials’ matrix and shows its effect on enhancing their figure of merit.
