“…However, the absorption coefficient of the film deposited at 400 • C corresponding to the CuO phase strongly decreases to 2 × 10 3 cm −1 in the infrared (λ > 1600 nm), due to the non-crystallization of the tetragonal CMTS phase. These high absorption coefficients are consistent with other reports [41,42] and are considered as suitable absorber layer in thin film solar cell.…”

The direct synthesis of chalcopyrite Cu2MnSnS4 (CMTS) thin films by a spray pyrolysis technique on glass substrates under oxidative conditions (ambient atmosphere and using compressed air as a carrier gas instead of nitrogen) was studied. The effect of the deposition temperature on the structural, chemical composition, and optical and electrical properties of thin films has been assessed. X-ray diffraction study reveals that the tetragonal stannite structure crystallizes with a [112] preferential orientation from 280 up to 360 °C, with its crystallinity correlated with the substrate temperature. However, in addition to its crystallization, traces of secondary phases are observed: a mixture of SnO and CuO at 360 °C prevails on the formation of CuS at 320 °C. Above 360 °C, the oxidant conditions combined with the loss in sulfur lead to the crystallization of only the tenorite CuO. The crystallization of sulfides by spray pyrolysis under air is possible only at relatively low deposition temperature for which the oxidation rate is inefficient compared to the sulfidation rate. Further optical studies of stannite films indicate a high absorption coefficient toward the visible range (>104 cm−1) and an optical band gap of about 1.64–1.85 eV, also depending on the substrate temperature. The CMTS thin films deposited below 360 °C exhibit a moderate electrical resistivity of about Ω·cm at room temperature. The properties of the stannite films synthesized using a spray pyrolysis technique in ambient air are comparable to those of films obtained by spray pyrolysis with nitrogen carrier gas despite the presence of oxides traces, an increase in the deposition temperature improving the microstructure, and its related optical and electrical properties.

“…These attractive features along with the sufficient abundance to annual production ratio provided by Ni make Cu 2 NiSnS 4 (CNTS) worth to be considered for TW range PV applications. Currently, few works on CNTS are present in the literature, most of them reporting on thin films prepared by non-vacuum techniques, namely electrodeposition followed by sulfurization (Chen et al, 2016b; Yang et al, 2016), spray sandwich method (Dridi et al, 2017; Bitri et al, 2018) and direct solution coating followed by sulfurization (Mokurala et al, 2017). As expected, the layer morphology was generally found to be strongly dependent on the substrate, the larger grain size being obtained on SLG due to the higher diffusion of Na from the substrate.…”

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.

“…105,106 There are currently a few literature reports on CNTS thin lm solar cells and most of the studies have employed non-vacuum techniques like electrodeposition, spraying, and direct liquid coating. [107][108][109][110] Some of the limiting factors in increasing the efficiency of CZTS solar cells are the Cu-on-Zn and Zn-on-Cu antisite disorders. 111 CBTS does not exhibit these cation-cation antisite disorders and is a promising candidate for achieving higher efficiencies in thin lm solar cells.…”
