Lead sulfide and antimony trisulfide are obtained through the vacuum thermal decomposition of Jamesonite. However, in this process, the microscopic mechanism and stability, which affects their deep separation, is unclear. This mechanism was explored under vacuum conditions using thermodynamics and molecular dynamics calculations along with experimental research. At 5 Pa, PbS decomposes and volatilizes at 1173 K and Sb 2 S 3 volatilizes at 923 K. The dynamic simulation results show that PbS are more likely to decompose and generate Pb and S 2 than Sb 2 S 3 . The fracture mode of the bond in the thermal decomposition process of PbS is layer-by-layer expansion between layers. The binding ability of Sb atoms and S atoms is also relatively strong, and the binding volatilizes outward in the form of Sb 2 S 3 . In addition, according to the vacuum distillation experiment, 5 Pa and 923-973 K are considered to be the best separation conditions for separating PbS and Sb 2 S 3 . Under this condition, Sb 2 S 3 is completely volatilized, while PbS is neither volatilized nor decomposed, and the separation rate reaches the maximum. Therefore, this study clarified the decomposition and volatilization mechanism of PbS and Sb 2 S 3 at the theoretical level, and provided guidance for sulfide separation experiments.

Sb 2 S 3 has been proven to be a very promising light absorbing material for photovoltaic applications due to its low cost, high stability, non-toxicity, and abundant elemental storage. Electron transport layer (ETL) is a very crucial factor to the performances of Sb 2 S 3 solar cells. Here we developed a simple chemical solution process method to synthesize SnO 2 colloidal and fabricated SnO 2 ETL at low-temperature first, and then SnO 2 /CdS double ETL was prepared by combining SnO 2 and CdS. The power conversion efficiency of Sb 2 S 3 solar cell is 5.3% based on the SnO 2 /CdS double ETL, whereas the device based on CdS ETL only exhibites a PCE of 4.3%. Experimental analyses revealed that the introduction of SnO 2 ETL enhanced the grain size of Sb 2 S 3 films and passivated interfacial defects thus enhancing device efficiency. Our results show the potential application of SnO 2 in the planar Sb 2 S 3 solar cell.

In this study, a rod-like heterogeneous Bi 2 S 3 /Sb 2 S 3 was systematically engineered through a simple one-step hydrothermal method and subsequently used as an anode active material for sodium-ion batteries (SIBs). The Bi 2 S 3 /Sb 2 S 3 heterostructure electrode exhibits a high initial discharge capacity of 972.2 mAh g −1 and maintains a reversible capacity of 369.4 mAh g −1 after 500 cycles at a current density of 1 A g −1 . The outstanding electrochemical performance of the Bi 2 S 3 /Sb 2 S 3 electrode can be attributed to the synergistic contributions of the high capacity of Sb 2 S 3 and the excellent stability of Bi 2 S 3 . Simultaneously, the abundant heterogeneous phase boundaries formed by Bi 2 S 3 and Sb 2 S 3 provide stable reaction interfaces, better structural integrity, and enhanced Na + reaction kinetics. This work presents an opportunity to develop heterogeneous Bi 2 S 3 /Sb 2 S 3 anode materials with excellent properties, holding promise for potential applications in SIBs.

Antimony sulfide (Sb 2 S 3 ) with high absorption coefficient reveals great potential for photodetectors (PDs) in various fields of military and national economy. A new type of depleted Sb 2 S 3 thin film photoconductive detector by using titanium dioxide (TiO 2 ) interlayer with the structure of Au/(glass/TiO 2 :)Sb 2 S 3 /Au is designed. Compared with normal Au/Sb 2 S 3 /Au devices, the depleted Sb 2 S 3 PDs obtain a higher switching ratio of 90, greatly enhancing responsivity and specific detectivity. Owing to the electric field of the depletion region, the response time significantly decreases from 23.2 to 0.6 ms. In addition, the anisotropic Sb 2 S 3 film with [120] dominated horizontal orientation is suitable for polarized light detection. The peak-to-valley ratio of the depleted Sb 2 S 3 PD reaches 1.3 at polarized light. The results and methods of this study are expected to expand the application of PDs based on Sb 2 S 3 films.

Surface and interface engineering have shown broad application prospect in energy conversion. Mo 2 C-C/Sb 2 S 3 composites have been synthesized by coupling Mo 2 C-C composites and Sb 2 S 3 nanowires with coupling agent. The performance of the devices has been investigated. Under irradiation by light source, the device showed better electrical contact, fast response speed (rise time 0.135 s, decay time 0.132 s) and larger on/off ratio ( 1 . 5 × 1 0 2 ) than the device which assembled by mechanical mixing ( 1 × 1 0 2 ) and pure Sb 2 S 3 nanowires (47), respectively. The performance has been enhanced by modifying the surface and interface of materials. This approach provides a new idea to enhance the high-performance photodetectors and other inventive optoelectronic devices.

The noble-metal-free surface-enhanced Raman scattering (SERS) substrates have gained significant attention due to their abundant sources, signal uniformity, biocompatibility, and chemical stability. However, the lack of controllable synthesis and fabrication methods for high-SERS-activity noble-metal-free substrates hinders their practical applications. In this study, we demonstrate the use of a femtosecond laser direct writing technique to precisely manipulate and modify microstructures, resulting in enhanced SERS signals from Sb2S3 nonmetal-oxide semiconductor materials. Compared with unpatterned Sb2S3 samples, the Sb2S3 microstructures exhibited up to a 16-fold increase in Raman scattering intensity. Interestingly, our results indicate that the femtosecond laser can induce a transformation in the crystalline state of Sb2S3 and significantly enhance the Raman spectrum signal within the Sb2S3 microstructures. This enhancement is also highly dependent on the period and depth of the microstructures, possibly due to the cavity effects, resulting in a stronger local field enhancement.

An Sb2S3-sensitized TiO2(Sb2S3/TiO2) photo-anode (PA) exhibiting a high photo-electrochemical (PEC) performance in water oxidation has been successfully prepared by a simple chemical bath deposition (CBD) technique. Herein, the Raman spectra and XPS spectrum of Sb2S3/TiO2confirmed the formation of Sb2S3on the TiO2coatings. The Sb2S3/TiO2photo-anode significantly shifted the absorption edge from 395 nm (3.10 eV) to 650 nm (1.90 eV). Furthermore, the Sb2S3/TiO2photo-anode generated a photo-anodic current under visible light irradiation below 650 nm due to the photo-electrochemical action compared with the TiO2photo-anode at 390 nm. The incident photon-to-current conversion efficiency (IPCE = 7.7%) at 400 nm and −0.3 V vs. Ag/AgCl was 37 times higher than that (0.21%) of the TiO2photo-anodes due to the low recombination rate and acceleration of the carriers of Sb2S3/TiO2. Moreover, the photo-anodic current and photostability of the Sb2S3/TiO2photo-anodes improved via adding the Co2+ions to the electrolyte solution during photo-electrocatalysis.Keywords:Sb2S3/TiO2;photo-anode;long wavelength;photo-electrochemical;water oxidation

Sb 2 S 3 has garnered significant attention in photovoltaic applications due to its suitable bandgap, single stable orthogonal phase and excellent stability. However, due to the coexistence of indirect transition parts in the bandgap, a thicker Sb 2 S 3 absorption layer is usually required to achieve decent light absorption in solar cells, which inevitably leads to an increase in trapped states in the bulk. Therefore, it is of great importance to realize more photogenerated carriers without increasing charge recombination. Here, we realized the in-situ growth of high-quality Sb 2 S 3 micropillar arrays on the template prepared by laser direct writing. Compared with the traditional thick layer, this array structure with less material usage can not only achieve more light absorption by enhancing photon scattering, but also optimize carrier transport at the interface by expanding their contact area with the hole transporting layer. This work provides a strategy for controllably achieving enhanced light absorption of Sb 2 S 3 structures, which is a perspective for the improvement of highly efficient solar cells.

Sb 2 S 3-x Se x (0 ≤x ≤ 3) is promising for practically applicable solar cell since it possesses excellent stability, suitable band gap, high extinction coefficient and abundant elemental storage. This study demonstrates a novel methodology towards simultaneous dissolution of Se and Sb 2 O 3 for direct deposition of Sb 2 S 3-x Se x films. Mechanistic study shows that the formation of selenium-nitrogen free radical in sulfur-containing complex is responsible for the dissolution of selenium. The energy levels of the as-synthesized Sb 2 S 3-x Se x were examined by synchrotron radiation photoemission spectroscopy , revealing that more Se in the Sb 2 S 3-x Se x leads to the valence band shifting considerably upward while the conduction band remaining nearly unchanged. Moreover, for the first time we present that the solution processed Sb 2 S 3-x Se x can generate photovoltaic performance with an efficiency of 5.8%. This research provides a straightforward strategy for the fabrication of Sb 2 S 3-x Se x solar cells and offers an effective method for the synthesis of metal selenosulfide films.

Graphical An aqueous solution process was used to generate flat, compact, and carbon free Sb 2 S 3 films, leading to high efficiency in planar heterojunction Sb 2 S 3 solar cells. 3-mercaptopropionic acid was applied as both solvent and sulfur precursor, and aqueous ammonia was employed as a solvent. Planar heterojunction solar cell based on the as-prepared Sb 2 S 3 film delivered a power conversion efficiency of 5.57 %. Sb 2 S 3 is a new kind of photovoltaic material that is promising for practical application in solar cells owing to its suitable bandgap, earth-abundant elements, and excellent stability. Here, we report on an aqueous-solution-based approach for the synthesis of Sb 2 S 3 films from easily accessible Sb 2 O 3 as antimony source. In this reaction, 3-mercaptopropionic acid was applied as both solvent and sulfur precursor, aqueous ammonia was employed as a solvent. After simple annealing at a temperature as low as 270 °C, the spin-coated precursor solution can generate compact, flat, uniform, and well-crystallized Sb 2 S 3 film. Mechanistic study showed that the formation of Sb-complex with ammonium carboxylates leads to the successful dissolution of Sb 2 O 3 powder. A suitable annealing process was able to generate carbon-free Sb 2 S 3 films. Planar heterojunction solar cell based on the as-prepared Sb 2 S 3 film delivered a power conversion efficiency of 5.57 %, which is the highest efficiency of solution-processed planar heterojunction Sb 2 S 3 solar cells and a high value in all kinds of Sb 2 S 3 solar cells. This research provides a convenient approach for the fabrication of device-quality Sb 2 S 3 films, and highlights solution processing of carbon-free metal chalcogenide thin films as a suitable process for application in optoelectronic devices.

Sb 2 S 3 thin film solar cells have been attracting much attention because of its excellent the photoelectric properties. By now, all the works on Sb 2 S 3 solar cell were focused on the Sb 2 S 3 thin film solar cells with sensitized structure or superstrate structure. However, Sb 2 S 3 solar cell with substrate structure was rarely reported. The substrate structure of the Sb 2 S 3 solar cell has unique advantages in device interface optimization, film growth, and application on flexible devices, and so on. The study of the substrate structure has great significance for improving the efficiency of the device and expanding its application range. In this work, Sb 2 S 3 thin films were deposited on Mo-coated glass substrate by the rapid thermal evaporation (RTE) method. The Sb 2 S 3 thin film quality is improved by combining adjusting the substrate temperature and evaporation time. Finally, a 1.75% efficient Sb 2 S 3 thin film solar cells with the substrate configuration of SLG/Mo/Sb 2 S 3 /CdS/i-ZO/AZO/Ni:Al was fabricated. Experimental and SCAPS simulation results show that deep level defects in the absorber layer and interface of the absorber layer and the buffer layer are the main reason for limiting the efficiency of devices.

Tremendous efforts have been focusing on the improvement of p-type (Bi, Sb) 2 Te 3 -based thermoelectric materials for commercial applications. In this study, we achieve versatile interface engineering through a surface decoration of Bi 0.5 Sb 1.5 Te 3 by amorphous Sb 2 S 3 combining with spark plasma sintering, which introduces semi-coherent Sb/Bi 0.5 Sb 1.5 Te 3 interfaces and dopes S into Bi 0.5 Sb 1.5 Te 3 . Semi-coherent Sb/Bi 0.5 Sb 1.5 Te 3 interfaces strongly scatter phonons and lower energy carriers, leading to decreased thermal conductivity and increased Seebeck coefficient, while the electrical conductivity is not sacrificed due to the compromise of the slightly reduced carrier mobility by interfacial scattering and the increased carrier concentration by S doping. Benefited from the decoupled thermoelectric properties, a significantly enhanced power factor of 3345.40 μW m −1 K −2 and a low thermal conductivity of 0.78 W m −1 K −1 is obtained in Bi 0.5 Sb 1.5 Te 3 -0.4%Sb 2 S 3 , leading to a high peak zT of ∼ 1.31 at 330 K, which shows a 54% enhancement compared with pristine Bi 0.5 Sb 1.5 Te 3 . Moreover, a conversion efficiency of ∼ 7.6% can be predicted in a single leg Bi 0.5 Sb 1.5 Te 3 -0.4%Sb 2 S 3 -based module under a cold side temperature of 300 K and hot side temperature of 480 K. This study paves a facile amorphous Sb 2 S 3 induced interface engineering strategy for the development of high performance (Bi,Sb) 2 Te 3 -based thermoelectric materials.
