The volatilization of stibnite (Sb 2 S 3 ) in nitrogen from 700 to 1000 °C was investigated by using thermogravimetric analysis. The results indicate that in inert atmosphere, stibnite can be volatilized most efficiently as Sb 2 S 3 (g) at a linear rate below 850 °C, with activation energy of 137.18 kJ/mol, and the reaction rate constant can be expressed as k =206901exp(−16.5/ T ). Stibnite can be decomposed into Sb and sulfur at temperature above 850 °C in a nitrogen atmosphere. However, in the presence of oxygen, stibnite is oxidized into Sb and SO 2 gas at high temperature. Otherwise, Sb is oxidized quickly into antimony oxides such as Sb 2 O 3 and SbO 2 , while Sb 2 O 3 can be volatilized efficiently at high temperature.

Compact thin film of antimony sulfide (Sb 2 S 3 ) as a promising absorber layer was obtained by rapid thermal evaporation (RTE) rather than conventional chemical bath deposition or atomic layer deposition based methods. The systematical characterizations of Sb 2 S 3 film demonstrated the pure phase, void free and high crystallization. The large grain and preferential growth of Sb 2 S 3 thin film were implemented by crystallization and cooling techniques, respectively. The corresponding devices were gradually optimized with a power conversion efficiency of ~3.5%, almost three times of planar devices fabricated by vacuum method. Both the non-oxide buffer layer (CdS layer) and free of hole transport layer enabled the high stability of the non-encapsulated planar devices. The high throughput and reliable RTE fabrication technique , environment-friendly and earth-abundant Sb 2 S 3 materials, stable and superior device performances were expected to drive the research progress of Sb 2 S 3 thin film photovoltaics .

Antimony sulfide can be produced by vacuum distillation of lead antimony sulfide ore. In this paper, the volatilization kinetics of antimony sulfide under vacuum conditions was studied for the first time using a self-made vacuum furnace, and the stability of antimony sulfide was explained through thermodynamic calculations. The results show that under a system pressure of 20 Pa and a temperature range of 873 K–1073 K, the apparent volatilization activation energy of antimony sulfide is 57.6 kJ/mol, and the volatilization control step of antimony sulfide is a gas phase diffusion process. As the temperature increases from 873 K to 1073 K, the volatilization rate of antimony sulfide increases from 0.20 g cm −2 min −1 to 0.88 g cm −2 min −1 by 4.4 times. As the system pressure increases from 20 Pa to 100 Pa, the volatilization rate of antimony sulfide decreases rapidly, decreasing by nearly 11.4 times. Antimony sulfide will not decompose within the range of system pressure above 20 Pa and temperature below 1073 K.

Antimony sulfide (Sb 2 S 3 ) solar cells have attracted extensive attention in silicon-based tandem solar cells. The performance of Sb 2 S 3 devices fabricated by the vacuum method is limited by sulfur vacancies ( V S ) and surface oxide defects during high-temperature processes. Herein, amorphous Sb 2 S 3 film based on low-temperature rapid thermal evaporation (RTE) technique is fabricated to overcome S loss. Moreover, a sulfur-atmosphere recrystallization strategy is further developed to obtain high-quality absorbers from the amorphous film. The element content of Sb 2 S 3 film is completely in accord with the stoichiometric ratio (2:3), and the surface oxides are effectively suppressed, enhancing V OC and fill factor. Compared to the control directly crystallized film, the defect concentrations of the S-recrystallized Sb 2 S 3 film are reduced by 61%, exhibiting better uniformity and higher PN junction quality. Ultimately, the full-inorganic Sb 2 S 3 solar cells (FTO/TiO 2 /Sb 2 S 3 /Au) achieve an efficiency of 6.25%. The S-atmosphere recrystallization process can effectively passivate bulk defects ( V S and Sb 2 O 3 ) and suppress recombination to improve device performance, which will provide new prospects for vacuum method-based Sb 2 S 3 thin film solar cells.

Sb 2 S 3 has been paid extensive attentions as absorber for solar cells. Comparing with some oxides , CdS exhibits excellent compatibility to Sb 2 S 3 therefore is most commonly used as buffer layer (BL) materials for Sb 2 S 3 solar cells. Proper passivation can enhance the performance of CdS buffer layer thus raising the performances of Sb 2 S 3 solar cells. Herein, we put forward a self-passivation strategy to enhance the performance of CdS by a two-step deposition process to fabricate the self-passivated CdS BL. First, we adopted spin coating combined with annealing process to prepare flaked CdS on FTO, then we performed passivation process to the CdS by depositing another layer of CdS with chemical bath deposition (CBD) method. After Sb 2 S 3 was deposited on the self-passivated CdS by hydrothermal method , a solar cell with FTO/CdS (∼90 nm)/Sb 2 S 3 (160 nm)/Spiro-OMeTAD(48 nm)/Ag(32 nm)structure was obtained by deposition of hole transport layer and Ag electrodes. Comparing with the single spin-coating processed CdS BL or single chemical bath deposited CdS BL, the self-passivated CdS presents better performance. The CBD process presents distinctive passivation effects to the first layer. In consequence, we obtained the highest PCE of 6.04 % in the Sb 2 S 3 solar cells on the self-passivated CdS BL. The present work supplies a unique route to enhance the performances of CdS buffer layer.

Enhancement of birefringence is significant since the birefringent materials can create and control polarized light and be used extensively in various advanced optical systems. By optimizing the arrangement of [SbS3] units with stereo-chemical active lone pair electrons, a new quaternary thioantimonate LiSrSbS3 with a large birefringence has been successfully synthesized by a high temperature solid-state reaction method. LiSrSbS3 crystallizes in the monoclinic space group of P21/c. In the structure, the isolated infinite [LiS4] chains and zigzag [SrS6] chains are alternately connected with each other to compose a three-dimensional (3D) framework, and the isolated pyramid [SbS3] units are located between them. To analyze the source of large birefringence, the electronic structure and optical properties of LiSrSbS3 were further investigated by the first-principles method, and the results show that the optimized arrangement [SbS3] trigonal pyramid induces a large birefringence.

The controllable preparation of materials with unique structures and morphologies has become an important field in the development of nanomaterials . In this study, Sb 2 S 3 was used as the evaporation source to controllably prepare Sb 2 S 3 crystals with various morphologies under a vacuum. At 873 K and 30 min, antimony sulfide in the form of cauliflower-like was effectively made. At the same temperature and for 60 min, tubular antimony sulfide was formed. The initial forming conditions of fascicle-like antimony sulfide were at 873 K and 100 min and did not change with the increase in temperature. During the evaporation process, some antimony sulfide will condense into lumps, showing irregular feather-like and round particles. The products prepared by this method were analyzed and tested. The results showed that the grade of antimony sulfide prepared by this method was further improved, and the content of Sb and S increases by 1.64% and 1.21% on average. This method offers a simple production process, a more regular product shape, and does not require the use of any additives.

Thioantimonates containing high oxidation state Sb5+ have been proven to exhibit excellent performance in the design of new materials such as infrared optical crystals and lithium-ion batteries. However, as described by the “inert pair effect”, the preparation of P-block elements containing high oxidation states in sealed systems has been a challenge. In this study, an aliovalent cation substitution strategy was used to design and synthesize three novel thioantimonates(V), A4BaSb2Se8 (A = Cs, Rb) and Rb2BaSbS4Cl (RBSSC), respectively, all of which contain rare [SbS4] tetrahedral units. The introduction of Ba2+ ions leads to the distortion and high-density arrangement of [SbSe4] units, which is manifested as a significant 3.7 times enhancement of the birefringence compared to that of the parent compound Cs3SbSe4 (0.041 → Cs4BaSb2Se8 0.150@1064 nm). By further introducing highly electronegative halogen atoms, the first antimony-based thiohalide(V) RBSSC was synthesized. Theoretical calculations show that the band gap of RBSSC is up to 3.674 eV, larger than those of all known antimony-based thiohalides(III). This work provides strong evidence that the aliovalent cation substitution strategy is an effective way to find new thioantimonate(V) families, and also indicates that the cation size effect introduced by elemental substitution may lead to surprising performance improvements.

The sulfide-based solid electrolyte (SSE) has been considered as a strong candidate for potential uses in all-solid-state lithium batteries (ASSLBs). Nevertheless, most of the reported SSEs are plagued with their intrinsic air-sensitive behaviors and Li-incompatibility, which largely preclude scalable fabrication and widespread practical application. Herein, we report the Li6+xSb1−xSnxS5I (LSSSI-x) SSEs using nontoxic inexpensive Sn substitution to deal with these issues. The ionic conductivity of Li6+xSb1−xSnxS5I can achieve a maximum value of 3.49 × 10−4 S cm−1 at room temperature when x = 0.4, which is over 40-fold that of the pristine Li6SbS5I. The Li symmetric cell with I-rich Li6.4Sb0.6Sn0.4S5I (LSSSI-0.4) electrolyte delivers a stable Li+ plating/stripping behavior over 450 h at a current density of 0.1 mA cm−2. Benefiting from the decent Li-compatibility of LSSSI-0.4, the assembled ASSLB with LiNi0.8Co0.1Mn0.1O2-based composite cathode and Li-metal anode displays good cycling performance. The LSSSI-0.4 electrolyte also possesses excellent moisture stability. ASSLB using the dried LSSSI-0.4 electrolyte still exhibits a well-maintained initial discharge capacity of 184.0 mA h g−1 at 0.1C and an impressive capacity retention rate of 70.6% after 600 cycles at 0.2C. This work offers a feasible option with superior integrated properties to push forward the advancement of high-performance ASSLBs.

Considered the promising anode material for next-generation high-energy lithium-ion batteries, SiO x has been slow to commercialize due to its low initial Coulombic efficiency (ICE) and unstable solid electrolyte interface (SEI) layer, which leads to reduced full-cell energy density, short cycling lives, and poor rate performance. Herein, a novel strategy is proposed to in situ construct an artificial hybrid SEI layer consisting of LiF and Li 3 Sb on a prelithiated SiO x anode via spontaneous chemical reaction with SbF 3 . In addition to the increasing ICE (94.5%), the preformed artificial SEI layer with long-term cycle stability and enhanced Li + transport capability enables a remarkable improvement in capacity retention and rate capability for modified SiO x . Furthermore, the full cell using Li(Ni 0.8 Co 0.1 Mn 0.1 )O 2 and a pre-treated anode exhibits high ICE (86.0%) and capacity retention (86.6%) after 100 cycles at 0.5 C. This study provides a fresh insight into how to obtain stable interface on a prelithiated SiO x anode for high energy and long lifespan lithium-ion batteries.

The fabrication of a flexible thermoelectric (TE) device that contains flexible, all-inorganic hybrid thin films (p-type single-wall carbon nanotubes (SWCNTs)/Sb 2 Te 3 and n-type reduced graphene oxide (RGO)/Bi 2 Te 3 ) is reported. The optimized power factors of the p-type and n-type hybrid thin films at ambient temperature are about 55 and 108 µW m −1 K −2 , respectively. The high performance of these films that are fabricated through the combination of vacuum filtration and annealing can be attributed to their planar orientation and network structure. In addition, a TE device, with 10 couples of legs, shows an output power of 23.6 µW at a temperature gradient of 70 K. A prototype of an integrated photovoltaic-TE (PV-TE) device demonstrates the ability to harvest low-grade “waste” thermal energy from the human body and solar irradiation. The flexible TE and PV-TE device have great potential in wearable energy harvesting and management.

It is imperative yet challenging to efficiently sequester the 137Cs+ ion from aqueous solutions because of its highly environmental mobility and extremely high radiotoxicity. The systematical clarification for underlying mechanism of Cs+ removal and elution at the molecular level is rare. Here, efficient Cs+ capture is achieved by a thioantimonate [MeNH3]3Sb9S15 (FJSM–SbS) with high capacity, fast kinetics, wide pH durability, excellent β and γ radiation resistances, and facile elution. The Cs+ removal is not significantly impacted by coexisting Na+, K+, Ca2+, Mg2+, and Sr2+ ions which is beneficial to the remediation of Cs+-contaminated real waters. Importantly, the mechanism is directly illuminated by revealing an unprecedented single-crystal to single-crystal structural transformation upon Cs+ uptake and elution processes. The superior Cs+ removal results from an unusual synergy from strong affinity of soft S2– with Cs+, easily exchangeable [MeNH3]+ cations, and the flexible and robust framework of FJSM–SbS with open windows as trappers.
