Owing to its outstanding photoelectric characteristics, Sb 2 S 3 has witnessed rapid development as a light-absorbing material for solar cells. However, the traditional utilization of Spiro-OMeTAD and PbS as hole transport layers (HTLs) in Sb 2 S 3 solar cells poses significant challenges regarding stability and environmental toxicity. In this work, a solution-processed high-quality and smooth molybdenum oxide (MoO x , 2 ≤ x ≤ 3) HTL is successfully applied in Sb 2 S 3 solar cells, boosting the fill factor from 15.37% to 53.00% and efficiency from 0.36% to 4.47% respectively, thereby presenting a cost-effective, eco-friendly, and non-toxic alternative to conventional HTLs. To address the roll-over effect observed in the J–V curves, attributed to back-contact recombination in the device, sodium ascorbate, a reducing agent, is introduced into the precursor solution to modulate the valence states of molybdenum (+4, +5, +6), which generates diverse interstitial energy levels. These energy levels are anticipated to facilitate band alignment optimization and enhance hole extraction efficiency. Remarkably, the Sb 2 S 3 device incorporating this novel MoO x HTL achieves an impressive efficiency of 4.47%, representing the highest reported efficiency for Sb 2 S 3 solar cells employing a green, and stable HTL. This work provides new insights for the development of green and non-toxic Sb 2 S 3 devices.

Antimony sulfide (Sb2S3) solar cells exhibit significant potential in tandem and indoor photovoltaic applications. The quality of cadmium sulfide (CdS)/Sb2S3 heterojunction, affected by energy-level misalignments and lattice-mismatch defects, is crucial for achieving high-performance devices. Herein, we propose a MgCl2-CdCl2 mixed treatment strategy for the CdS/Sb2S3 interface to suppress interfacial recombination caused by defects and energy band offsets. The obtained preferentially [100]-oriented CdS film effectively mitigates lattice mismatch and induces the subsequent hydrothermal deposition of a well-crystallized, vertically oriented Sb2S3 absorber. The MgCl2-CdCl2 mixed treatment introduces Mg2+ doping in the CdS layer, achieving an enhanced surface potential and well-matched interfacial energy band alignments. The CdS/Sb2S3 heterojunction interface forms a spike-type energy band structure with a small conduction band offset. Compared with the conventional CdCl2 treatment, the MgCl2-CdCl2 mixed-treated device exhibits a stronger built-in electric field (1.31 V) and low-temperature activation energy (1.63 eV), indicating the suppression of carrier recombination. Consequently, the champion Sb2S3 solar cells achieve an improved efficiency from 7.5% to 8.1%. This heterojunction treatment strategy is expected to provide an effective method for fabricating high-performance inorganic thin film solar cells.

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.

Antimony sulfide (Sb 2 S 3 ) photodetectors (PDs) show great prospects in applications of optical communication and imaging. The detector performance is significantly influenced by reflection losses at the incident surface, particularly under weak-light conditions. Herein, we propose self-powered Sb 2 S 3 thin film PDs (glass/ITO/patterned ITO/TiO 2 /Sb 2 S 3 /Au) with light-trapped ITO patterns to enhance absorbance and performance. Periodic cuboid-patterned ITO patterns with the sizes of 50 × 50 µm 2 and depth of 250 nm are fabricated using photolithography and magnetron sputtering, which achieves about a 21% absorbance enhancement of visible light and 16% photocurrent increase of Sb 2 S 3 PDs. Meanwhile, the patterned ITO slightly expands the heterojunction contact area, which enhances the built-in electric field and the carrier extraction efficiency. Under the 530-nm light illumination of 5 µW/cm 2 , the device achieves a responsivity of 4.5 A/W and a specific detectivity of 1.4 × 10 13 Jones, demonstrating its weak-light detection ability. The Sb 2 S 3 PDs array, featuring fast response and a wide 3 dB bandwidth, has demonstrated image sensing capabilities by clearly resolving variations in bright and dark fields, showcasing application potentials.

Sb 2 S 3 has attracted much attention due to its high absorption coefficient, abundant elemental reserves and stable chemical properties. However, key issues such as interface recombination and poor energy level matching have restricted the improvement of device performance. This study investigated the effects of three electron transport layers (ETLs), CdS, TiO 2 and SnO 2 , on the hydrothermal quasi-epitaxial growth of Sb 2 S 3 . CdS could induce the formation of a continuous and dense Sb 2 S 3 film through S-Sb chemical bridge bonds, while TiO 2 and SnO 2 , due to their surface inertness, led to island-like growth of Sb 2 S 3 , accompanied by interface holes and defects. Device test results indicated that the device with CdS as the ETL had the best performance: power conversion efficiency (PCE) of 6.11 %, the lowest saturation current density ( J 0 ), and effective suppression of interface recombination. Devices with TiO 2 and SnO 2 as ETLs exhibited lower open-circuit voltage ( V oc ) and short-circuit current density ( J sc ), and poor device performance (2.82 % and 1.09 %) due to severe interface recombination. SCAPS-1D simulation further confirmed that CdS had significant advantages in energy level matching and interface defect control, making it the most suitable ETL among the three for the quasi-epitaxial growth of Sb 2 S 3 , providing a key reference for the development of high-efficiency Sb 2 S 3 solar cells.

Antimony sulfide (Sb 2 S 3 ), characterized by its high theoretical capacity and favorable reaction kinetics, has been extensively investigated as a promising conversion anode for sodium−ion batteries (SIBs). However, its substantial volume changes and intrinsically low electrical conductivity affect the SIB performance. Herein, one–dimensional (1D) Sb 2 S 3 nanotubes coated with polyvinylpyrrolidone (PVP) derived carbon and anchored onto a conductive network of carbon nanotubes (CNTs) (Sb 2 S 3 /PVP@CNTs) are elaborately designed by tailoring the pH of antimony electrolyte (Na 3 SbS 3 ) solution. Experimentally, the Sb 2 S 3 /PVP@CNTs composites as an anode provide a considerable reversible capacity of 368 mAh g −1 in SIBs at 1 A g −1 after 200 cycles. The formation of interfacial Sb–O–C bonds is attributed to the synergistic interaction of –OH groups in CNTs, PVP, and Sb 3+ throughout its lifecycle, as validated by X–ray photoelectron spectroscopy (XPS) results. Theoretical calculations strongly evidence that the narrower bandgap can enhance electrochemical kinetics and reaction reversibility. Crucially, this study provides a novel and scalable strategy for the synergistic development of green metallurgy and advanced energy storage systems.

The structure and properties of the Sb 2 S 3 films were characterized by XRD, SEM, TEM and electrochemical workstation. The results show Sb 2 S 3 films mainly consist of orthorhombic phase with micro-nanorods morphology. Sb 2 S 3 films exhibit good electrocatalytic activity towards hydrazine oxidation with a low detection limit of 0.4 μM. The facile synthesis method and excellent sensing properties make the Sb 2 S 3 films as a promising candidate for potential application in the field of catalysis and environmental.

Sb 2 S 3 is a promising candidate for the flexible solar cells or the top subcells in tandem solar cells due to its wide-bandgap, less toxic, acceptable cost and progressive power conversion efficiency (PCE). However, the poor quality and high trap states of Sb 2 S 3 films limit the device performance further enhancement. Herein, we adopt a multidentate ionic liquid , tetramethylammonium hexafluorophosphate ([TMA][PF 6 ]) as a novel additive to address this issue. The octahedral [PF 6 ] − contains six different oriented fluorine atoms with the lone pair electrons , which could coordinate with Sb atoms due to the multidentate anchoring. Thus, the high-quality Sb 2 S 3 film with low trap states has been achieved. Moreover, the Fermi level of the Sb 2 S 3 film has been upshifted, thereby showing an effective charge transfer. As a result, all photovoltaic parameters of the optimized Sb 2 S 3 devices are obviously enhanced, boosting the final PCE from 4.43 (control device) to 6.83 %. Our study about the multidentate anchoring is manifested to be an effective method to enhance the Sb 2 S 3 device performance.

Effects of Pb on thermal stability and crystallization kinetics of chalcogenide glasses (1− x )(0.85GeS 2 −0.15Sb 2 S 3 )− x PbS ( x = 0–0.4) have been carried out by a detailed calorimetric study and structural analysis. The glass stability was assessed based on three criteria, while the activation energies of crystallization were calculated under nonisothermal crystallization conditions by the Kissinger method, the Augis/Bennett method, the Mahadevan method, and the modified Ozawa method, respectively. Both stability criteria and activation energies of crystallization suggest that the glasses possess excellent thermal stability. The thermal stability decreases with addition of PbS but is insensitive to the content of PbS in the range from x = 0.1 to 0.4. Raman, XRD, and molar volume structural characterization suggested that the excellent thermal stability of these glasses is due to the glass former role of PbS. The calculated Avrami exponent pointing to a 3-dimensional crystallization mechanism which explains the reason for the previously reported successful preparation of infrared transmitting chalcogenide glass-ceramics.

Antimony-based materials with high capacities and moderate potentials are promising anodes for lithium-/sodium-ion batteries. However, their tremendous volume expansion and inferior conductivity lead to poor structural stability and sluggish reaction kinetics. Herein, a double-confined nanoheterostructure Sb/Sb 2 S 3 @Ti 3 C 2 T x @C has been fabricated through a solvothermal method followed by low-temperature heat treatment. The dual protection of “MXene” and “carbon” can better accommodate the volume expansion of Sb/Sb 2 S 3 . The strong covalent bond (Ti–S, Ti–O–Sb, C–O–Sb) can firmly integrate Sb-based material with Ti 3 C 2 T x and carbon, which significantly improves the structure stability. In addition, the carbon layer can restrain the oxidation of MXenes, and the nano-Sb/Sb 2 S 3 can facilitate electron/ion transport and suppress the restacking of MXenes. The heterogeneous interface between Sb and Sb 2 S 3 can further promote interfacial charge transfer. The MXene-Sb/Sb 2 S 3 @C-1 with the optimal Sb content shows high specific capacities, comparable rate properties and ultra-stable cycling performances (250 mAh·g −1 after 2500 cycles at 1 A·g −1 for sodium-ion batteries). Ex situ X-ray diffractometer (XRD) test reveals the storage mechanism including the conversion and alloying process of MXene-Sb/Sb 2 S 3 @C-1. Cyclic voltammetry (CV) test results demonstrate that the pseudocapacitance behavior is dominant in MXene-Sb/Sb 2 S 3 @C-1, especially at large current. This design paves the way for exploring high-performance alloy-based/conversion-type anode for energy storage devices. Graphical abstract

Antimony sulfide (Sb 2 S 3 ) has emerged as a promising absorber material for thin-film solar cells due to its excellent light absorption properties. However, its inherent quasi-one-dimensional crystal structure and complex defect landscape severely limit device V OC and J SC . In this study, lead-doped Sb 2 S 3 was achieved through an ion exchange method, and Sb 2 S 3 :Pb thin films were subsequently prepared via vapor transport deposition(VTD). The incorporation of Pb doping promoted preferential [hk1] orientation growth, facilitating vertical carrier transport channels across the substrate. Concurrently, it significantly reduced the Urbach energy, enhanced carrier concentration, and effectively suppressed non-radiative recombination through the formation of shallow-level Pb Sb defects alongside reduced defect density of deep-levlel Sb i . The optimized device achieved V OC of 709 mV, J SC of 12.99 mA/cm 2 , and a power conversion efficiency of 5.22%, establishing a new record efficiency for Sb 2 S 3 solar cells fabricated by VTD. This work provides an effective strategy for improving Sb 2 S 3 thin-film quality through cation doping and advances its development in photovoltaic applications.

Antimony sulfide (Sb 2 S 3 ) is a promising absorber for photovoltaics operating under both outdoor and indoor illumination due to its suitable bandgap and excellent photostability. However, during chemical bath deposition, the unsynchronized hydrolysis and sulfidation of Sb 3+ species induce excessive homogeneous nucleation, leading to amorphous particles and ultimately films with small grains, high grain boundary density, and low crystallinity. To address this issue, an rGO-regulated deposition strategy is developed. The oxygen-containing functional groups on rGO can interact with Sb 3+ species through coordination and electrostatic interactions, thereby modulating their local availability and reaction kinetics. This suppresses homogeneous nucleation and promotes substrate-guided growth, yielding Sb 2 S 3 films with [ hk 1] preferred orientation, enlarged grains, reduced defects, and improved carrier transport. As a result, the photovoltaic device with rGO-regulated achieves a PCE of 7.61% under AM 1.5G illumination (compared to 7.15% for the conventional CBD device) and 17.64% under 3000 K, 1000 lux warm white LED illumination. This work highlights Sb 2 S 3 as a versatile absorber for outdoor–indoor photovoltaics and provides a pathway for regulating solution-phase crystallization.
