“…Although several reports agree in the identification of the main Raman peak of each structure (i.e. 290 cm −1 for CTS m , 303 cm −1 for CTS c and 337 cm −1 for CTS t ) 26 , 53 , 54 , numerous contradictions have been reported in the assignment of other modes related to the three CTS structures. These confusions concern mainly the modes at 351 cm −1 that was attributed either to CTS c 27 or to CTS t 55 – 57 , and at 352 cm −1 assigned to CTS m 19 , 26 , 29 , 49 , 57 , 58 or to CTS t structure 59 .…”

Cu2SnS3 (CTS) is emerging as a promising absorber for the next generation thin film solar cells (TFSC) due to its excellent optical and electronic properties, earth-abundance and eco-friendly elemental composition. In addition, CTS can be used as precursor films for the Cu2ZnSnS4 (CZTS) synthesis. The optical properties of CTS are influenced by stoichiometry, crystalline structure, secondary phases and crystallite size. Routes for obtaining CTS films with optimized properties for TFSC are still being sought. Here, the CTS thin films synthesized by magnetron sputtering on soda lime glass (SLG) using Cu and SnS2 targets in two different stacks, were studied. The SLG\Cu\SnS2 and SLG\SnS2\Cu stacks were annealed in S and Sn + S atmospheres, at various temperatures. Both stacks show a polymorphic structure, and higher annealing temperatures favor the monoclinic CTS phase formation. Morphology is influenced by the stacking order since a SnS2 top layer generates several voids on the surface due to the evaporation of SnS, while a Cu top layer provides uniform and void-free surfaces. The films in the copper-capped stack annealed under Sn + S atmosphere have the best structural, morphological, compositional and optical properties, with tunable band gaps between 1.18 and 1.37 eV. Remarkably, secondary phases are present only in a very low percent (< 3.5%) in samples annealed at higher temperatures. This new synthesis strategy opens the way for obtaining CTS thin films for solar cell applications, that can be used also as intermediary stage for CZTS synthesis.

“…Further details regarding the device fabrication process can be found in our previous reports. [22,47,48] Absorber and Device Characterizations: The crystal structure of the CTS thin film was examined using high-resolution XRD (X'-pert PRO, Philips, Netherlands) operated at 40 kV and 30 mA with Ni-filtered Cu Kα radiation (λ ¼ 1.5418 Å) in the 2θ range 10 to 70 with a step size of 0.02 , an integration time of 1 s, and using a Pixel and X'Celarator detector. Micro-Raman spectroscopy (LabRam HR 800 UV Raman microscope, Horiba Jobin-Yvon, France at the KBSI Gwangju Center) was conducted at an excitation wavelength of 515 nm and a resolution of 0.23 cm À1 at a power level of 10% of a 10-mW laser to record Raman spectra in a range of 50-400 cm À1 .…”

Cu2SnS3 (CTS) has various crystal structures and a wide bandgap energy range of 0.93–1.77 eV, depending on the crystal structure. The optical properties of CTS are very similar to those of Cu2ZnSnS4 (CZTS)‐based materials, as reported extensively in the past and is therefore in the spotlight as an absorber material. However, CTS thin film solar cells (TFSCs) are mainly studied on non‐flexible substrates, and little research has been focused on flexible substrates. When a flexible substrate is applied to CTS TFSCs, Zn is omitted from CZTS‐based materials, reducing raw material costs and enabling a roll‐to‐roll fabrication process; hence, the economic benefit is doubled. When CTS TFSCs are fabricated on a Mo foil substrate, voids exist at the back interface and the device characteristics markedly deteriorate. To solve this problem, the thickness of the CTS absorber layer is increased in this study by doubling the thickness of the precursor. As a result, Cu, Sn, and S display a more uniform distribution in the absorber layer, which further improves the light‐absorbing characteristics of CTS TFSCs. Finally, a device with a power conversion efficiency of 1.31% is obtained.

In this work, self‐charging pouch‐type hybrid supercapacitor (HSCs) is fabricated by extrinsic integration of wind and solar energy power systems. Initially, the synthesized mesoporous 3D‐rhombohedral Mn2O3 shows a specific capacity of 37.61 mA h g−1 in KOH plus redox additives electrolyte. Further, the oxygen vacancy of Mn2O3 is tuned by fast‐reduction (FR) and mild‐reduction (MR) techniques. The rich oxygen vacancy of FR‐Mn2O3 (rich Ov‐Mn2O3) exhibits a specific capacity of 66.64 mA h g−1. On the other hand, the different morphologies of Cu2SnS3@SnS are synthesized by time‐dependent solvothermal technique. The 3D‐microsphere Cu2SnS3@SnS shows higher electrochemical performance than the others. In order to further improve the electrochemical performance, the heterostructure of rich Ov‐Mn2O3@Cu2SnS3@SnS composite is prepared that provides a maximum specific capacity of 126.07 mA h g−1 at 8 mA cm−2 and rate capability of 66.09% with retention of 93.89% after 10 000 cycles. This is ascribing to high electrical/ionic conductivity, larger faradaic reactions, lower interfacial resistance, and synergistic effect. Then, the fabricated pouch‐type HSC delivers a maximum specific energy density of 47.97 Wh kg−1 and power density of 5120 W kg−1. Finally, the pouch HSCs are employed for practical self‐charging applications.
