Solar energy conversion into electricity through photovoltaic technology represents an environmentally friendly way of utilizing renewable energy sources for sustainable energy production. Low-cost and highly stable Sb2S3 solar cells are considered promising photovoltaic materials. However, Sb2S3 solar cells are currently facing problems such as poor electron transport capacity and grain boundary defects. In this work, an Sb2S3 precursor solution is prepared by the sol–gel method, to which a small amount of cesium is added for doping the light absorbing layer. By exploring the doping concentration, the optimal doping concentration of 0.05% is obtained. The doped Sb2S3 exhibits improved crystallinity, reduces surface roughness, increases particle size, decreases grain boundaries, and enhances carrier transport capacity, which is reflected in the increased open-circuit voltage (Voc = 0.678 V), short-circuit current density (Jsc = 15.92 mA/cm2), and power conversion efficiency (PCE = 4.81%). Cs doping effectively suppresses recombination centers by forming S–Cs metal bonds, thereby reducing impurities and reducing film surface defects, which collectively enhance the quality of Sb2S3 films. This study provides valuable insights and strategies for the further modification and optimization of Sb2S3 solar cells.

Antimony (Sb) based compounds such as Sb 2 O 3 and Sb 2 S 3 have shown promises in electronics, catalysis and sensing devices. Their functional performances can be further improved by integration with other materials to from composites or heterostructures, which however, usually require tedious procedures with poor morphology control. Herein, we realized direct hydrothermal synthesis of Sb 2 O 3 /SnO 2 heterostructures and Sb 2 S 3 /SnS 2 heterostructures by using liquid-phase exfoliated two-dimensional (2D) Sb nanoflakes as precursors. Compared to directly using SbCl 3 salt as the reactant, using the Sb nanoflakes enabled the slow release of Sb 3+ ions which benefited the better controlled nucleation and growth of Sb 2 O 3 (or Sb 2 S 3 ) acting as growth templates for the further deposition of SnO 2 (or SnS 2 ). As a demonstration, the as-prepared Sb 2 S 3 /SnS 2 heterostructures were employed for photocatalytic methylene blue (MB) degradation, which exhibited a faster degradation rate compared to Sb 2 S 3 or SnS 2 alone. Our work offers an alternative strategy with elemental 2D materials as precursors for the preparation of heterostructured functional materials.

Antimony sulfide (Sb₂S₃) is a highly promising environmentally friendly semiconductor for the development of stable thin-film solar cells, owing to its high absorption coefficient, suitable bandgap ( ~ 1.7 eV), and the abundance of its constituent elements. Conventionally, CdS is employed as a buffer layer in CdS/Sb₂S₃/spiro/Au-structured solar cells. However, due to its intrinsic defects, various strategies have been implemented to enhance device performance and improve the power conversion efficiency (PCE) of Sb₂S₃ solar cells. In this study, we first fabricated a SnO₂ electron transport layer (ETL) and subsequently optimized the water bath temperature to achieve a smoother CdS layer. Furthermore, a La³⁺ ion doping process was introduced to further decrease the resistance of the CdS layer. The incorporation of an appropriate concentration of La³⁺ into the CdS layer effectively redeced its resistivity. By integrating these enhancements, we developed a La-doped CdS/SnO₂ double ETL structure. The grain size of Sb₂S₃ deposited on the 1% La-doped CdS/SnO₂ double ETL was significantly increased, leading to a substantial reduction in grain boundary density. This improvement minimized non-radiative recombination at both the grain boundaries and the CdS/Sb₂S₃ heterointerface while simultaneously enhancing charge-carrier transport across the heterojunction. Consequently, the optimized solar cell achieved an open-circuit voltage (V OC ) of 749 mV and a short-circuit current density (J s c ) of 17.01 mA/cm 2 , resulting in a power conversion efficiency (PCE) of 7.66%. This work presents an effective doping strategy to enhance the performance of the CdS buffer layer, offering valuable insights for the advancement of Sb₂S₃-based thin-film solar cells.

Antimony sulfide (Sb 2 S 3 ) has great potential as a promising wide–bandgap, low–cost, low–toxicity, and stable photovoltaic material for next–generation indoor and tandem photovoltaic applications. This article reports that there are competitive chemical reaction mechanisms during hydrothermal preparation of Sb 2 S 3 , and we present an effective strategy to control these mechanisms using the anionic surfactant sodium dodecyl sulfate (SDS) as a reaction additive. We found that the SDS additive significantly enhances the hydrothermal heterogeneous reaction path and thus improves the quality of the Sb 2 S 3 absorber by shifting the balance between homogeneous and heterogeneous reactions. An efficiency of 6.84% under standard AM1.5 illumination irradiance is achieved. The SDS–optimized Sb 2 S 3 solar cells also show remarkably high indoor photovoltaic performance. An efficiency as high as 16.37% is reported under indoor illumination by a 1000 lx white light LED source. This result indicates the excellent prospects of Sb 2 S 3 in a broad range of photovoltaic applications.

Antimony sulphide (Sb 2 S 3 ) thin films have attracted considerable research interest as a photovoltaic absorber material owing to their suitable band gap, large absorption coefficient, and excellent photoelectronic properties. In this study, cadmium sulphide (CdS) films were doped with potassium , which increased their crystallinity and optical transmission . These films were then used as a buffer layer to increase the efficiency of Sb 2 S 3 solar cells. Furthermore, the potassium diffused into the Sb 2 S 3 film, which increased their crystallinity and light absorption and decreased its surface roughness. Dual-functional potassium doping helped improve all of the photoelectric parameters of the Sb 2 S 3 solar cells. Specifically, the device efficiency increased from 4.57% to 6.53% (an increase of 42.89%), and a high current density of 15.29 mA cm −2 was achieved. These findings are expected to facilitate the further development of Sb 2 S 3 thin-film solar cells for industrial applications.

A novel Sb 2 O 3 /Sb 2 S 3 /FeOOH photoanode was fabricated via a simple solution impregnation method along with chemical bath deposition and post-sulfidation. The X-ray diffractometry, Raman measurement, and X-ray photoelectron spectroscopy show that the Sb 2 O 3 /Sb 2 S 3 /FeOOH thin films are successfully prepared. SEM−EDS analyses reveal that the surface of Sb 2 O 3 /Sb 2 S 3 thin films becomes rough after the immersion in the FeCl 3 solution. The optimized impregnation time is found to be 8 h. The FeOOH co-catalyst loaded Sb 2 O 3 /Sb 2 S 3 electrode exhibits an enhanced photocurrent density of 0.45 mA/cm 2 at 1.23 V versus RHE under simulated 1 sun, which is approximately 1.41 times compared to the photocurrent density of the unloaded one. Through the further tests of UV−Vis spectroscopy, the electrochemical impedance spectra, and the PEC measurements, the enhancement can result from the increased light-harvesting ability, the decreased interface transmission impedance, and the remarkably enhanced carrier injection efficiency.

In the emerging Sb 2 S 3 -based solar energy conversion devices, a CdS buffer layer prepared by chemical bath deposition is commonly used to improve the separation of photogenerated electron-hole pairs. However, the cation diffusion at the Sb 2 S 3 /CdS interface induces detrimental defects but is often overlooked. Designing a stable interface in the Sb 2 S 3 /CdS heterojunction is essential to achieve high solar energy conversion efficiency. As a proof of concept, this study reports that the modification of the Sb 2 S 3 /CdS heterojunction with an ultrathin Al 2 O 3 interlayer effectively suppresses the interfacial defects by preventing the diffusion of Cd 2+ cations into the Sb 2 S 3 layer. As a result, a water-splitting photocathode based on Ag:Sb 2 S 3 /Al 2 O 3 /CdS heterojunction achieves a significantly improved half-cell solar-to-hydrogen efficiency of 2.78% in a neutral electrolyte, as compared to 1.66% for the control Ag:Sb 2 S 3 /CdS device. This work demonstrates the importance of designing atomic interfaces and may provide a guideline for the fabrication of high-performance stibnite-type semiconductor-based solar energy conversion devices.

Jamesonite (Pb 4 FeSb 6 S 14 ) is a complex antimony sulfide mineral and an important raw material for the extraction of lead and antimony. Under vacuum conditions, the internal interaction mechanism of PbS and Sb 2 S 3 during thermal decomposition is unclear and difficult to separate. In order to explore the interaction mechanism between PbS and Sb 2 S 3 , the thermodynamic data of Pb-S and Sb-S systems were firstly calculated by thermodynamic calculation method, PbS and Sb 2 S 3 cluster substances that may exist in the gas phase were obtained under the given temperature conditions. On this basis, ab initio molecular dynamics was used to calculate the mean square displacement and diffusion coefficient of PbS and Sb 2 S 3 gas phase clusters. The vacuum distillation experiments of lead sulfide and antimony trisulfide confirmed the volatilization and diffusion of PbS and Sb 2 S 3 , and verified the theoretical calculation results. According to the experiment, the volatilization temperature of Sb 2 S 3 is much lower than that of PbS. The theoretical calculation results are consistent with the experimental results, which indicates that the calculation of the diffusion properties of PbS and Sb 2 S 3 gas phase clusters by molecular dynamics simulation is reliable. This is also an effective and simple method to predict whether the mixed melt of PbS and Sb 2 S 3 can be separated, which provides theoretical guidance for the vacuum separation of PbS and Sb 2 S 3 .

Dielectric properties of stibnite concentrate, pure antimony sulfide, three different desulfurizers and their mixtures were assessed using resonant cavity perturbation technique. Dielectric properties of ZnO and CaO are largely independent of temperature, while CuO and Sb 2 S 3 have strong dependency with temperature. For the mixtures, the Sb 2 S 3 + CuO exhibit strong responsiveness to microwave from 25 °C to 400 °C. The CuO could be efficiently heated and reacted with Sb 2 S 3 in microwave field, in agreement with thermodynamic result. Based on the dielectric properties and thermochemical characteristics during the desulfurization process, the phase evolution and reaction mechanism were systematically investigated. Results show that the majority of antimony elements in the concentrate were volatilized in the form of Sb 2 O 3 and the rest were left in the form of Sb. Effects of roasting temperature, desulfurizer dosage, and holding duration on microwave roasting were assessed and roasted sample were subjected to XRD, EDX and SEM analysis. Optimum roasting conditions were identified to be 700 °C, 1.4 times the stoichiometric requirement of CuO additive and holding duration of 1.5 h. Microwave roasting of stibnite concentrate with CuO additive promises to be a better alternative technology for traditional pyrometallurgical antimony roasting.

Antimony sulfide is an emerging 1D nontoxic Earth-abundant photovoltaic material with favorable wide bandgap as a suitable top-cell candidate for multijunction tandem solar cells. However, the current fabrication technology for Sb 2 S 3 solar cells relies heavily on a high-purity Sb 2 S 3 source, which limits its large-scale deployment. Therefore, it is attractive to fabricate the Sb 2 S 3 solar cells directly from the raw stibnite source, which can be cost effective by avoiding the complicated, costly purification and refinement process of the stibnite ore, while reducing process-emitted pollution. Herein, high-quality Sb 2 S 3 films (thickness: ≈1 μm) by the vapor transport deposition of raw stibnite ore powder are obtained, followed by a sulfurization process to remove the surface oxides and facilitate alkali element redistribution. In this way, the particle size is increased from ≈500 nm to ≈1.5 μm, the carrier concentration of the Sb 2 S 3 film is increased from ≈10 15 to ≈10 16 cm −3 , and the power conversion efficiency of Sb 2 S 3 solar cell is increased by more than two times. Through the elemental distribution analysis, it is found that it is the redistribution of alkali elements introduced from the natural stibnite ore that induces the grain growth, contributes toward defect suppression, and leads toward enhanced device performance.

Herein, a facile, one-step hydrothermal method is used to synthesize a 3D, symmetric, flowerlike Sb 2 S 3 nanostructure. The structure was composed of numerous nanoneedles, which provided a large void fraction and specific surface area. Characteristic mesoporous structures of the samples contribute to excellent performance. If they were used as counter electrode materials in dye-sensitized solar cells, the photoelectric conversion efficiency was as high as 7.12 %, whereas the photoelectric conversion efficiency of platinum was only 6.46 %. Furthermore, according to the results of cyclic voltammetry, electrochemical impedance spectra, and Tafel polarization testing, the obtained Sb 2 S 3 samples have better electrocatalytic activity and charge-transfer ability than that of Pt, and thus, can be regarded as good substitutes for precious metals.
