“…Formation of CTS nanocrystals with a zincblende structure in the presence of elemental sulfur has been proposed by many groups. , Cations are distributed in a different manner in wurtzite and zincblende structures. In the case of wurtzite, both Cu and Sn cations occupy a similar Wyckoff site, whereas these cations are distributed in a disordered manner in zincblende. ,,,− , The arrangement of cations in the anionic lattice plays an important role in the transport of carriers as well as the electronic band structure. , …”

“…In contrast, Cu 2 SnS 3 (CTS), while having desirable electrical/optical properties for photovoltaic applications, being a ternary compound, control of chemical composition and phase purity is practically simpler compared to CZTS. Additionally, concerning the commercialization, the presence of less elements in the compound is preferred. − …”

We investigate the use of simple nontoxic Cu 2 SnS 3 (CTS) nanoparticles (NPs) as low-cost dopant-free hole-transport materials (HTMs) a substitute for spiro-OMeTAD in an n-ip mesoscopic architecture of perovskite solar cells (PSCs). Besides, this work confirms the critical role of the crystalline phase of CTS NPs on the performance of the device. Using a facile one-pot heating-up procedure, pure zincblende and wurtzite structures of CTS NPs were obtained by sulfur element and thiourea as the sulfur source, respectively, and were dispersed in chloroform to make very stable nonpolar ink that is compatible with the perovskite. Nanoparticles with the wurtzite crystal phase showed much better photovoltaic performance compared to the zincblende phase with efficiencies of 13.01 and 7.87%, respectively. The efficiency of the reference solar cell using spiro-OMeTAD was 16.01%. Results from impedance spectroscopy and external quantum efficiency show that by switching from wurtzite-CTS to zincblende-CTS, the resistance of charge transfer at the perovskite/HTM interface is increased, which matches with the descending trend of fill factor of the corresponding cells. According to the morphological characteristics and electrical properties of HTM layers, the better performance of wurtzite-CTS in comparison with zincblende-CTS is due to two factors: (i) enhancement of the band-gap energy and alignment of the valance band maximum; and (ii) uniform smooth coverage of the perovskite film by monodispersed wurtzite-CTS NPs.

“…At this annealing temperature, short circuit current, open circuit voltage, fill factor and power conversion efficiencies were 1.12mA/cm 2 , 0.03V, 0.26, and 0.009% respectively [27]. On the other hand, the photovoltaic performance of Cu 4 SnS 4 thin films was studied in [36] achieving a power conversion efficiency of 2.4%. III.…”

Ternary compounds such as Cu4SnS4 thin films can be deposited onto glass substrates by various deposition methods: electrodeposition, chemical bath deposition, successive ionic layer adsorption and reaction, and evaporation techniques. Cu4SnS4 films could be used in solar cell applications because of their suitable band gap and large absorption coefficient. This paper reviews previous researches on Cu4SnS4 thin films. X-ray diffraction showed that the obtained films are orthorhombic in structure and polycrystalline in nature. Cu4SnS4 films exhibited p-type electrical conductivity and indicated band gap values in the range of 0.93 to 1.84eV.

Its main application field is photovoltaic 50 , however, it has been also found as an interesting thermoelectric material [51][52][53][54] . The TE performance can be enhanced by doping with Mn 55 , Fe 56 , Zn 57 , Co 58 and Ni 59 .…”

In this work, Cu based sulfides (chalcopyrite CuFeS 2, mohite Cu 2 SnS 3, tetrahedrite Cu 12 Sb 4 S 13 , mawsonite Cu 6 Fe 2 SnS 8 and kesterite Cu 2 ZnSnS 4 ) were synthesized by industrial milling in an excentric vibration mill to demonstrate scalability of their synthesis. For comparison, laboratory scale milling in a planetary mill was performed. The properties of the obtained samples were characterized by X-ray diffraction, and in some cases, also by Mössbauer spectroscopy. For densification of powders the method of Spark Plasma Sintering was applied to prepare suitable samples for thermoelectric (TE) characterization which created the core of this paper. Comparison of the figure-of-merit ZT, representative of the efficiency of thermoelectric performance, show that the scaling process of mechanochemical synthesis leads to the similar values than using laboratory methods. This makes the cost effective production of Cu-based sulfides as prospective energy materials for converting heat to electricity feasible. Several new concepts have been developed involving combinations of natural and synthetic species (tetrahedrite) and nanocomposite formation (tetrahedrite/digenite, mawsonite/stannite) offer sustainable approaches in solid state chemistry. Mechanochemical synthesis is selected as a simple, one-pot and facile solid-state synthesis of thermoelectric materials with the capability to reduce, or even eliminate solvents, 3 toxic gases, high temperatures with controllable enhanced yields. The synthesis is environmentally friendly and essentially waste-free. The obtained results illustrate the possibility of large-scale deployment of energy-related materials.
