“…Apart from the peaks marked with a red or green arrow, all other experimental peaks could be assigned to the monoclinic Cu 2 SnS 3 phase (JCPDS: 04-010-5719, see blue vertical lines), which was discussed by Onoda et al [13]. This phase is also the expected one at the used annealing temperature of 550 °C [13]. The marked peaks (red or green arrows) could be assigned to Mo (red) and MoS 2 (green).…”

“…While the band gap value of 1.51 eV measured by Kuku et al appears to be very high, values between 0.93 and 1.35 eV for the band gap seem to be dependent on the crystal structure of the polymorphic compound Cu 2 SnS 3 , where 0.98 eV was measured for a cubic phase and 1.35 eV for a tetragonal phase [11]. The polymorphic state of a grown Cu 2 SnS 3 is dependent on the growth temperature, where the cubic Cu 2 SnS 3 is known to form at high temperatures (> 775 °C) and the monoclinic and triclinic as well as the tetragonal phases are low temperature phases (< 775 °C) [13,14]. For this work, the samples have been prepared at temperatures where a monoclinic or triclinic phase can be expected.…”

Alongside with Cu 2 ZnSnS 4 and SnS, the p-type semiconductor Cu 2 SnS 3 also consists of only Earth abundant and low-cost elements and shows comparable opto-electronic properties, with respect to Cu 2 ZnSnS 4 and SnS, making it a promising candidate for photovoltaic applications of the future. In this work, the ternary compound has been produced via the annealing of an electrodeposited precursor in a sulfur and tin sulfide environment. The obtained absorber layer has been structurally investigated by X-ray diffraction and results indicate the crystal structure to be monoclinic. Its optical properties have been measured via photoluminescence, where an asymmetric peak at 0.95 eV has been found. The evaluation of the photoluminescence spectrum indicates a band gap of 0.93 eV which agrees well with the results from the external quantum efficiency. Furthermore, this semiconductor layer has been processed into a photovoltaic device with a power conversion efficiency of 0.54 %, a short circuit current of 17.1 mA/cm 2 , a open circuit voltage of 104 mV hampered by a small shunt resistance, a fill factor of 30.4 %, and a maximal external quantum efficiency of just less than 60 %. In addition, the potential of this Cu 2 SnS 3 absorber layer for photovoltaic applications is discussed.

“…1, the crystal structures of the former three are commonly composed of the CuS 4 and (Sb/Sn)S 4 tetrahedral units. [81][82][83] For the SbS 4 configuration, all valence electrons of Sb form covalent bonds with neighboring S atoms, leaving no lone-pair electrons. In Cu 4 SnS 4 , which contains CuS 3 , CuS 4 , and SnS 4 units, the Cu atoms in some sulfur tetrahedra vibrate with a large ADP along the orthorhombic b-axis (Figs.…”

Research Update: Cu–S based synthetic minerals as efficient thermoelectric materials at medium temperatures

Synthetic minerals and related systems based on Cu–S are attractive thermoelectric (TE) materials because of their environmentally benign characters and high figures of merit at around 700 K. This overview features the current examples including kesterite, binary copper sulfides, tetrahedrite, colusite, and chalcopyrite, with emphasis on their crystal structures and TE properties. This survey highlights the superior electronic properties in the p-type materials as well as the close relationship between crystal structures and thermophysical properties. We discuss the mechanisms of high power factor and low lattice thermal conductivity, approaching higher TE performances for the Cu–S based materials.

“…This cycle is based on the thermodynamic properties of kesterite, Cu 2 ZnSnS 4 [43], and kuramite. In kesterite, kuramite and mohite the crystal structure is organized on the same structural type, i.e., the tetrahedral arrangement of all cations within the framework derivative of that of sphalerite (ZnS) [44]. Thus, a close structural similarity between these phases is apparent.…”

Abstract:A relevant research effort is devoted to the synthesis and characterization of phases belonging to the ternary system Cu-Sn-S, mainly for their possible applications in semiconductor technology. Among all ternary phases, kuramite, Cu 3 SnS 4 , mohite, Cu 2 SnS 3 , and Cu 4 Sn 7 S 16 have attracted the highest interest. Numerous studies were carried out claiming for the description of new phases in the ternary compositional field. In this study, we revise the existing literature on this ternary system, with a special focus on the phases stable in a temperature range at 25˝C. The only two ternary phases observed in nature are mohite and kuramite. Their occurrence is described as very rare. A numerical modelling of the stable solid phases in contact with a water solution was underwent to define stability relationships of the relevant phases of the system. The numerical modelling of the Eh-pH diagrams was carried out through the phreeqc software with the lnll.dat thermodynamic database. Owing to the complexity of this task, the subsystems Cu-O-H, Sn-O-H, Cu-S-O-H and Sn-S-O-H were firstly considered. The first Pourbaix diagram for the two naturally relevant ternary phases is then proposed.
