Antimony selenide (Sb 2 Se 3 ) is a promising candidate for photodetector applications boasting unique material benefits and remarkable optoelectronic properties. Achieving high-performance self-powered Sb 2 Se 3 photodetector through a synergistic regulation of absorber layer and heterojunction interface demonstrates great potential and needs essential investigation. In this study, an effective two-step thermodynamic/kinetic deposition technique containing sputtered and selenized Sb precursor is implemented to induce self-assembled growth of Sb 2 Se 3 light absorbing thin film with large crystal grains and desirable [hk1] orientation, presenting considerable thin-film photodetector performance. Furthermore, aluminum (Al 3+ ) cation dopant is introduced to modify the optoelectronic properties of CdS buffer layer, and further optimize the Sb 2 Se 3 /CdS (Al) heterojunction interface quality. Thanks to the suppressed carrier recombination and enhanced carrier transport kinetics, the champion Mo/Sb 2 Se 3 /CdS (Al)/ITO/Ag photodetector exhibits self-powered and broadband characteristics, accompanied by simultaneously high responsivity of 0.9 A W −1 (at 11 nW cm −2 ), linear dynamic range of 120 dB, impressive ON/OFF switching ratio over 10 6 and signal-to-noise ratio of 10 9 , record total noise determined realistic detectivity of 4.78 × 10 12 Jones, and ultra-fast response speed with rise/decay time of 24/75 ns, representing the top level for Sb 2 Se 3 -based photodetectors. This intriguing work opens up an avenue for its self-powered broadband photodetector applications.

Antimony selenide (Sb 2 Se 3 ) is a potential absorber material for environment-friendly and cost-efficiently photovoltaics due to its material advantages and superior optoelectronic properties. In this work, we proposed a facile and versatile method of ball milling followed with spark plasma sintering (SPS) to prepare high-quality Sb 2 Se 3 sputtering target. Then the highly crystalline Sb 2 Se 3 thin film consisted of large crystal grains can be prepared by using radio frequency (RF) magnetron sputtering with an additional post-selenization heat treatment. An efficient substrate structured Sb 2 Se 3 thin film solar cell with configuration of Mo/Sb 2 Se 3 /CdS/ITO/Ag was fabricated and a champion device with highly interesting power conversion efficiency (PCE) of 5.08% has been achieved. Superior device performances are closely related to the Sb 2 Se 3 absorber layer with benign growth orientation and the Sb 2 Se 3 /CdS heterojunction interface with smooth contact, which induced less recombination loss . The combined features of homemade sputtering target and advantageous thin film preparation technology further demonstrated its attractive application potential in thin film photovoltaic scenarios.

Novel Sb 2 Se 3 /reduced graphene oxide (rGO) composite, 1D Sb 2 Se 3 nanorods wrapped with rGO, has been successfully synthesized by a facile spray drying method. Compared to as-prepared Sb 2 Se 3 nanorods, the obtained Sb 2 Se 3 /rGO composite, as anode for lithium-ion batteries (LIBs), exhibited super electrochemical performances. The results suggest that Sb 2 Se 3 /rGO composite can retain a reversible capacity of 394 mAh g −1 over 200 cycles at 100 mA g −1 between 0.01 and 3 V (vs Li/Li + ). Even at a high rate current density of 1000 mA g −1 , a discharge capacity of 247 mAh g −1 was computed, indicating that this LIB possesses good rate capability. This improved electrochemical performance can be attributed to the 1D nanostructure, and also to the introduction of rGO, which provided more electron transport pathways and shortened the Li-ion diffusion through the electrolyte. Consequently, the cluster of 1D Sb 2 Se 3 nanorods that are wrapped in the rGO nanostructure can efficiently buffer large volume changes and retain the structural stability during lithiation and delithiation process, resulting in an excellent electrochemical performance.

Antimony selenide (Sb 2 Se 3 ) thin films are light-absorbing materials used for low-cost, highly efficient thin-film solar cells. However, because it is deposited onto a comparatively rough substrate, stacking growth of a Sb 2 Se 3 thin film negatively impacts formation of the heterojunction. For this study, Sb 2 Se 3 thin-film solar cells were fabricated in a FTO/CdS/CeO 2 /Sb 2 Se 3 /Au configuration. An ultrathin layer of cerium dioxide (CeO 2 ) was deposited onto the CdS surface by evaporation, and the thickness of the CeO 2 interlayer was optimized to improve the photoelectric properties of the solar cells. Compared to the CdS surface in conventional Sb 2 Se 3 thin-film solar cells (FTO/CdS/Sb 2 Se 3 /Au), the surface of the CdS buffer in our solar cells was smoothed by the CeO 2 layer, which induced columnar growth of the Sb 2 Se 3 grains. Furthermore, diffusion of Ce 4+ into Sb 2 Se 3 enhanced its crystallinity and improved the evenness of the Sb 2 Se 3 thin-film surface. The photo-conversion efficiency (PCE) of a solar cell with a 2-nm thick CeO 2 interlayer reached 5.14%.

Sb2Se3 is a promising non-toxic, Earth-abundant, stable thin-film solar cell absorber material. However, the low built-in potential caused by the low intrinsic doping density (∼1013 cm−3) and the low carrier collection efficiency due to the low carrier mobility (∼1.5 cm2 V−1 s−1) hinder further efficiency improvement of Sb2Se3 solar cells. Therefore, an effective hole-transport layer (HTL) is necessary to further boost the built-in potential and assist carrier collection. Herein we attempt to improve the efficiency of Sb2Se3 solar cells by using CuSCN as an HTL. CuSCN as an HTL suppresses the back surface recombination, and enhances the built-in potential and carrier collection efficiency. Meanwhile, materials and physical properties characterization reveals that CuSCN provides Cu ions which induce grain boundary inversion, and therefore separate photo-generated carriers more efficiently. Consequently, we obtained a device efficiency of 7.50%.

Surface oxidation frequently occurs in non-oxide antimony chalcogenides, which is a double-edged sword for their (opto)electronic properties and applications. Here we report that the photoelectronic performance of Sb2Se3 nanorods (NRs) can be improved through an appropriate degree of surface oxidation. During the synthesis, the volume ratio of oleic acid (OA)/oleylamine (OLA) was varied to control the oxidation degrees of the Sb2Se3 NRs, which span 1.20–51.49% with increasing OA ratio as revealed by X-ray photoelectron spectroscopy (XPS) analysis. A medium level of surface oxidation, typically 20–30% found here, is beneficial to the enhancement of the photocurrent, on/off ratios and photostability of the Sb2Se3 NRs when evaluated in a sandwich-type ITO/Sb2Se3/ITO photoconductor device. Surface hydroxylation, which is boosted by the presence of Sb–oleate and trace H2O remaining in the reaction system, is suggested to facilitate the formation of Sb–OH bonds and the OA-volume dependent oxidation at the surface of Sb2Se3.

Sb 2 Se 3 is a promising absorber material for photovoltaic applications owing to its suitable bandgap and high absorption coefficient. However, the initial deposition of the precursor Sb 2 Se 3 thin films using thermal evaporation with an annealing process , results in poor crystallinity and inadequate Se content, leading to significantly low device efficiency and some deep-level detrimental defects. To address these issues, herein, we propose a facile thermal diffusion post-selenization method to supplement Se into post-deposited Sb 2 Se 3 thin films . This process not only achieves stoichiometric composition but also improves the crystallinity of the samples, thereby reducing defect density and carrier recombination. As a result, the efficiency of the fabricated Mo/Sb 2 Se 3 /CdS/ITO/Ag solar cell is significantly enhanced from 0.66% to 3.29%.

Antimony selenide (Sb 2 Se 3 ) has been applied extensively in the field of optoelectronics because of its excellent material and photoelectric properties, as well as its potential low cost effectiveness. Owing to its unique quasi-one-dimensional structure, the preparation of an Sb 2 Se 3 absorption layer with high crystallization quality and standing preferred orientation is crucial for constructing high-performance Sb 2 Se 3 devices. Herein, we reported a new method for the subsequent epitaxial growths of Sb 2 Se 3 thin films with high crystallization and preferred standing orientations using the Sb 2 Se 3 nanorod array as growth template on the Mo substrate and summarized the growth mechanism of the nanorod arrays. High crystal quality and crystal orientation can be easily controlled, carrier recombination is reduced, charge transport is enhanced, and the performance of Sb 2 Se 3 device is improved significantly. As high as 6.3 % power-to-efficiency with a fill factor of 62 % has been achieved for the champion device. This general-purpose nanorod array template growth film provides an effective reference for the growth control of other low latitude crystal films.

The good crystalline Sb 2 Se 3 nanorods have been successfully synthesized through a simple polyol process. The detailed morphological and structural characterizations reveal that nanorods are composed of Sb 2 Se 3 single crystals oriented along the [120] orientation; the tiny Sb 2 Se 3 nanorods are found to display a higher crystallinity with respect to thick Sb 2 Se 3 nanorods. The nanorods have been applied as anode materials for lithium-ion batteries, with tiny Sb 2 Se 3 nanorod anodes delivering the relatively high discharge capacity of 702 mAh g −1 at 0.1 C and could maintain the capacity of 230 mAh g −1 after 100 cycles. A more stable cycling performance is also demonstrated on tiny Sb 2 Se 3 nanorods, which is ascribed to their more pronounced one-dimensional nanostructure.

The coproduction of freshwater and electricity through solar-driven interfacial evaporation presents a promising strategy to address the current water and energy shortages. However, achieving high evaporation rate, efficient pollutant degradation, and high electrical power output in an integrated system remains challenging. Herein, we report a multifunctional membrane evaporator based on Sb 2 Se 3 /MoSe 2 /Ag heterostructures embedded in a polyacrylamide (PAM) hydrogel (Sb 2 Se 3 /MoSe 2 /Ag@PAM) for simultaneous wastewater evaporation, decontamination and thermoelectric power generation. The porous PAM matrix provided hydrophilicity and low evaporation enthalpy, while the heterostructures synergistically enhanced light absorption, photocatalytic activity, and thermal localization. As a result, under 1.0 sun illumination, the integrated membrane evaporator achieved a steady evaporation rate of 3.39 kg m −2 h −1 and a high degradation efficiency of 92% for tetracycline (TC) within 120 min, and when coupled with a thermoelectric module produced electricity with a maximum output power of 0.37 W·m −2 . Our work offers a new hybrid material platform comprising narrow bandgap semiconductor heterostructures, plasmonic noble metals and hydrogel membranes for high-performance multifunctional evaporators.

The influences of the selenium (Se) growth condition on the electronic level structure including deep defects and further on the photovoltaic conversion efficiency of antimony selenide (Sb 2 Se 3 ) as the solar cell absorber layer are investigated by controlling the Se powder content during the vapor transport deposition process. The detailed characterizations including X-ray diffraction, Raman, optical absorption and photoluminescence reveal that the deep defects including the Se vacancies on the Sb 2 Se 3 surface are largely reduced, and the efficiency of Sb 2 Se 3 solar cells can be significantly improved, e.g., by about 31% from 5.1% to 6.7% after adding excessive Se powder during the growth process. This result may provide a basic guideline for improving the efficiency of Sb 2 Se 3 solar cells during the growth process of the Sb 2 Se 3 absorption layer.

Sputtering followed by post annealing is extensively used for fabrication of copper indium gallium selenide (CIGS), copper zinc tin sulfide (CZTS) and copper zinc tin sulfur selenide (CZTSSe) thin film solar cells. In this work, Sb 2 Se 3 as an emerging alternative absorber was fabricated by an effective combination reaction of annealing sputtered Sb metallic precursors under Se vapor. Self-assembled growth of Sb 2 Se 3 thin films consist of large grains that across the whole films have been successfully fulfilled via this combination reaction. Sb 2 Se 3 thin films with desired orientation, stoichiometric composition and high-quality Sb 2 Se 3 /CdS heterojunction could be achieved once a proper selenization scenario was employed. Further, by selecting Sb films as precursors, the thickness of interfacial MoSe 2 located at the back-contact region can be well controlled, leading to a significant enhancement in fill factor (FF) of the devices. This is in good accordance with our DFT simulation results which demonstrated Se vapor would be prone to react with the Sb lattice thermodynamically and thus limiting the thickness of the MoSe 2 layer. Finally, a champion Sb 2 Se 3 thin film solar cell with power conversion efficiency of 6.15% was achieved, which represents the highest efficiency of sputtered Sb 2 Se 3 solar cells.
