“…These fabricated TEGs showed a significant performance improvement for a thin-film TEG as compared to other thinfilm TEGs using abundant, low-cost, and safer materials, which only show nanowatts 48,68 of power output. These chalcogenide/AZO TEGs may provide alternatives or insights into replacing scarce, expensive, and potentially harmful elements used in TE materials such as antimony (Sb), 44 tellurium (Te), 23,63 lead (Pb), 22,46 bismuth (Bi), 8,63 and germanium (Ge). 69 In conclusion, this work managed to demonstrate the fabrication of a working thin-film TEG using abundant and safer materials with a facile, low-cost, and scalable approach.…”

“…Several materials have been explored to fabricate these devices, including semiconductors, , fibers, and conducting polymers . In recent years, chalcogenide semiconductors such as lead telluride (PbTe) and bismuth telluride (Bi 2 Te 3 ) have been investigated for TE applications owing to their high power factors (PFs) due to the weaker covalent bonds on account of low electronegativity, along with the heavy atomic weights, which are beneficial in reducing thermal conductivity . Unfortunately, due to their composition of mostly toxic and scarce elements, the attention diverted toward more sustainable and abundant chalcogenides, such as tin selenide (SnSe), copper zinc tin sulfide (Cu 2 ZnSnS 4 , CZTS), − and copper tin sulfide (Cu 2 SnS 3 , CTS). − …”

In this work, Cu/Zn/Sn-based ternary and quaternary chalcogenides inks were synthesized via hot injection and/or from ball-milled powders. The synthesized inks were used to fabricate thermoelectric generators (TEGs) based on p-type chalcogenide and n-type aluminum-doped zinc oxide (AZO) thin films via spin-coating and magnetron sputtering, respectively. This work highlights the first-ever attempt in a facile and scalable method to fabricate thin-film TEGs using safe, low-cost, and abundant materials. Four different TEGs were fabricated using Cu 2 ZnSnS 4 (CZTS), Cu 2 ZnSnSe 4 (CZTSe), Cu 2.125 Zn 0.875 SnS 3 Se (CZTSSe), and Cu 2 SnS 3 (CTS) chalcogenides. Thermoelectric transport analysis confirmed the respective p-and n-type natures of the chalcogenides and AZO, with their Seebeck coefficients compatible to be coupled in a p−n device. In addition, a full-device analysis has been carried out, and several factors affecting the performance of TEGs were investigated, including the composition, density, and presence of secondary phases in chalcogenide thin films. The maximum power per unit active planar area obtained for CZTS, CZTSe, CZTSSe, and CTS TEGs at a temperature difference (ΔT) of 160 K was ∼43, ∼188, ∼23, and ∼59 nW/cm 2 , respectively, making CZTSe/AZO TEG the champion device.

“…Here, near-room temperature thermoelectric materials suitable for thermoelectric PTM can be classified into nonflexible and flexible types as summarized in Figure 6. Figure 6a and Table 1 summarize nonflexible thermoelectric materials with high near-room temperature thermoelectric performance, which are mainly are bulk inorganic materials, such as Bi 2 Te 3based, [80][81][82][83][84][85][86] Ag 2 Se-based, [87] and Mg 2 Bi 3 -based thermoelectric materials. [88] Among them, bulk Bi 2 Te 3 -based thermoelectric materials are the most well-developed and widely applied mainly due to their high S 2 σ values, which have approached the ultrahigh near-room temperature zT of 1.18 (300 K) of n-type Bi 2 Te 2.7 Se 0.3 [89] and 1.86 (320 K) of p-type Bi 0.5 Sb 1.5 Te 3 .…”

Thermoelectrics are energy harvesters that can directly convert waste heat into electrical energy and vice versa. Currently, thermoelectric (TE) devices display lower efficiency as the materials used for construction possess a very low figure of merit (ZT). Therefore, understanding the structural features of materials, finding new materials, and analyzing their chemistry and physics play a vital role in enhancing their energy conversion efficiency. Among the different classes of TE materials, some inorganic chalcogenides are perfect candidates for power generation as they possess excellent TE properties. The objective of this review is to provide insights into structural features and innovative methods to obtain enhanced thermoelectric properties of selected inorganic chalcogenides. The review covers recent advances in preparation methods, structural features, and thermoelectric properties of selected metal selenides (Bi2Se3, Ag2Se, SnSe, etc.) and metal tellurides (Bi2Te3, SnTe, PbTe, etc.). The review also discusses the critical parameters for designing and optimizing the TE materials to obtain the required electrical conductivity (σ), Seebeck coefficient (S), and thermal conductivity (k). In addition, promising mechanistic approaches to be adopted for enhancing the efficiency of TE materials such as doping, alloying, and nanostructuring are discussed in detail. Finally, a summary that describes advancements in the materials design is provided with a prospect for future applications from these materials in the development of energy harvesting technology.
