“…The S 2p core-level spectra exhibit the S 2p 1/2 and S 2p 3/2 peaks, registered around 162.7 and 161.6 eV, with a peak separation of about 1.1 eV, in agreement with the sulfide phases binding energies [36][37][38][39]. Therefore, in all the analyzed samples, the binding energy for Cu, Zn, Fe, Sn, and S confirmed that the primary chemical states are respectively + 1, + 2, + 2, + 4, and − 2, in agreement with the states in the Cu 2 (Zn,Fe)SnS 4 chemical formula [19]. Most of the oxygen is bound with the iron, suggesting substitution of S by O in the structure.…”

“…The C(Z,F)TS optical band gap is frequently reported as decreasing from 1.5 to 1.2 eV with increasing iron content [13][14][15][16][17]. Solution processing methods have proven to be very suitable to produce CZTS-based solar cells, though they require annealing in a sulfur vapor atmosphere to form the pure polycrystalline phase [15,18,19]. Here, we report a sol-gel procedure with drop-casting deposition to prepare C(Z,F)TS thin films for photovoltaic applications.…”

Photovoltaics is a promising technology to produce sustainable energy, thanks to the high amount of energy emitted by the sun. One way of having solar cells with low production costs is to apply thin-film technology and with earth-abundant raw materials. A keen interest is arising in kesterite compounds, which are chalcogenides composed of abundant and non-toxic elements. They have already achieved excellent performance at the laboratory level. Here, we report the synthesis and characterization of mixed chalcogenides based on copper, zinc, iron, and tin. Solutions have been studied with different zinc and iron ratios. The distortion of the elementary cell of kesterite increases with the addition of iron until a phase transition to stannite occurs. The process of synthesis and deposition proposed herein is cheap and straightforward, based on the sol-gel technique. These thin films are particularly attractive for use in cheap and easily processable solar cells. The synthesized layers have been characterized by X-ray diffraction, UV-Vis absorption, and Raman, X-ray photoelectron, and energy-dispersive X-ray spectroscopy measurements.

“…So far, various methods have been reported for the preparation of CFTS absorber layers (Guan et al, 2014; Kevin et al, 2015; Khadka and Kim, 2015; Meng et al, 2015a, 2016; Chatterjee and Pal, 2017; Chen et al, 2017; Miao et al, 2017). Most of them are based on non-vacuum techniques, since they are simple, low-cost, often efficient and do not require sophisticated deposition set-up.…”

At the end of 2017 roughly 1.8% of the worldwide electricity came from solar photovoltaics (PV), which is foreseen to have a key role in all major future energy scenarios with an installed capacity around 5 TW by 2050. Despite silicon solar cells currently rule the PV market, the extremely more versatile thin film-based devices (mainly Cu(In,Ga)Se 2 and CdTe ones) have almost matched them in performance and present room for improvement. The low availability of some elements in the present commercially available PV technologies and the recent strong fall of silicon module price below 1 $/W p focused the attention of the scientific community on cheap earth-abundant materials. In this framework, thin film solar cells based on Cu 2 ZnSnS 4 (CZTS) and the related sulfur selenium alloy Cu 2 ZnSn(S,Se) 4 (CZTSSe) were strongly investigated in the last 10 years. More recently, chalcogenide PV absorbers potentially able to face TW range applications better than CZTS and CZTSSe due to the higher abundance of their constituting elements are getting considerable attention. They are based on both MY 2 (where M = Fe, Cu, Sn and Y = S and/or Se) and Cu 2 XSnY 4 (where X = Fe, Mn, Ni, Ba, Co, Cd and Y = S and/or Se) chalcogenides. In this work, an extensive review of emerging earth-abundant thin film solar cells based on both MY 2 and Cu 2 XSnY 4 species is given, along with some considerations on the abundance and annual production of their constituting elements.

“…The micro-Raman spectroscopy assist in identifying the secondary phases and confirms the phase purity of the CFTS absorber powder material. Miao et al [10] have obtained Raman peaks at 318 and 284 cm −1 which are due to the CFTS nanoparticles. The peak obtained at 372 cm −1 is ascribed to Cu 2 Sn 3 S 7 (CTS) nanoparticles.…”

“…Physical techniques are expensive as their operation is difficult, and complex equipment and high vacuum are needed. On the other hand, chemical techniques are simple and cheap; there is low wastage of materials and no need for vacuum, making them suitable for large scale production [10,11]. Absorber nanomaterials show enhanced optical, chemical and mechanical properties in comparison to the bulk material.…”

Quaternary semiconductor Cu 2 FeSnS 4 (CFTS) nanoparticle powder have been prepared by a simple chemical technique. The synthesized CFTS nanoparticles have been characterized via powder XRD analysis, Raman spectra, FE-SEM-EDS, UV-Visible absorption spectroscopy, thermal analysis and electrochemical characterization. Powder XRD and Raman spectroscopy confirm the phase and structure of the prepared nanoparticles. The optical absorption studies reveal that the CFTS nanoparticles have a direct optimal band gap in the range from 1.32 to 1.5 eV, which indicates that these nanoparticles are potential absorber materials for thin-film photovoltaic application. The synthesized CFTS nanoparticles were transformed to the ink form and the obtained nanoparticle ink coated on a FTO conducting substrate (surface resistivity-13 Ω sq −1 ). The catalytic activity of the substrate was analyzed by electrochemical impedance spectroscopy (EIS) and cyclic voltammogram (CV) curves. The appropriate optical band gap and stable electrical properties indicate that Cu 2 FeSnS 4 Nanoparticles are potential materials for thin-film photovoltaic application.
