Anisotropic Sb2Se3 is an emerging earth-abundant photocathode for photoelectrochemical water splitting. However, controlling the growth of the Sb2Se3 film with optimal [001] crystallographic orientation is still the most challenging issue. Here, we successfully synthesized [001]-oriented Sb2Se3via a reliable and facile method. The [001]-oriented Sb2Se3 film could provide an excellent carrier-migration efficiency. Consequently, we achieved a record-high photocurrent density of −20.2 mA cm−2 at 0 VRHE and a very high half-cell solar-to-hydrogen efficiency of 1.36% under 1-sun simulated solar illumination in a TiO2/[001]-Sb2Se3 photocathode. This work provides an effective strategy and important guidelines for rationally designing optoelectronic devices based on the [001]-oriented Sb2Se3 film.

Although interfacial engineering materials for antimony selenide (Sb2Se3) photocathodes have been intensively studied, most of the previous research has focused on the development of photogenerated electron transfer promoters. In this work, Sb2Se3 photocathodes are innovatively modified by using ferrihydrite (Fh), which has been widely used as a hole storage layer in photoanodes. After modifying Fh, the photocurrent density of the Sb2Se3 photocathode was increased from −0.27 to −1.6 mA cm–2 at 0 VRHE with the onset potential positive shift about 150 mV, and an impressive injection efficiency of 83.84% was achieved. The major contribution of Fh to the photoelectrochemical (PEC) performance enhancement was demonstrated by various characterization studies. The results show that the enhancement performance of PEC is largely attributed to the capture of back-migrating holes by Fh, the reduction of interfacial charge transfer resistance, and the significant increase in electrochemical active surface area (ECSA). This work presents new insights into the application of hole storage layers in Sb2Se3-based photocathodes.

Aluminum batteries (ABs) are a promising alternative to lithium-ion batteries (LIBs) in the future. The development of aluminum batteries (ABs) is closely related to their cathode material. In this paper, we successfully designed and prepared a nanorod structure Sb 2 Se 3 @PPy as cathode material for ABs. It exhibits a high reversible capacity of 302 mAh/g at 0.2 A/g, and the capacity is maintained at about 210 mAh/g after 50 cycles. In addition, the electrochemical reaction mechanism and kinetic process of Sb 2 Se 3 @PPy were studied. The results showed that the PPy coating layer reduced the volume change of Sb 2 Se 3 , prevented irreversible deformation, enhanced the structural stability and electronic conductivity.

Originating from photovoltaic devices, self-powered photodetectors (SPPDs) have low power consumption and show promising applications in photoelectric imaging and optical communications. Many efforts have been devoted to improving their photodetection performances, including responsivity, detectivity, and response time. However, work on their operational stability, one of the key parameters of applied PDs, is still rare. Here, using an interfacial engineering method, we improve the operational stability of the representative Sb2Se3-based SPPD. The Sb2O3 modification layer is applied at the interface between the Sb2Se3 and TiO2 layers and characterized systematically. With the optimized fabrication of the Sb2O3 layer, the operational stability under both air ambient and underwater conditions is significantly enhanced. Moreover, the performances of the SPPD, including responsivity, detectivity, and response time, are improved to 0.45 A/W, 2.70 × 1013 Jones, and 81.5/75.0 ns, respectively. Specifically, without encapsulation, the photoresponse and key photodetection parameters of the devices vary by only around ten percent after working underwater. Our work provides a facile and effective way to modify the interfacial properties of the Sb2Se3 heterostructure and improve the operational stability of the SPPD.

Solar cells based on inorganic absorbers, such as Si, GaAs, CdTe and Cu(In,Ga)Se 2 , permit a high device efficiency and stability. The crystals’ three-dimensional structure means that dangling bonds inevitably exist at the grain boundaries (GBs), which significantly degrades the device performance via recombination losses. Thus, the growth of single-crystalline materials or the passivation of defects at the GBs is required to address this problem, which introduces an added processing complexity and cost. Here we report that antimony selenide (Sb 2 Se 3 )—a simple, non-toxic and low-cost material with an optimal solar bandgap of ∼ 1.1 eV—exhibits intrinsically benign GBs because of its one-dimensional crystal structure. Using a simple and fast ( ∼ 1 μm min –1 ) rapid thermal evaporation process, we oriented crystal growth perpendicular to the substrate, and produced Sb 2 Se 3 thin-film solar cells with a certified device efficiency of 5.6%. Our results suggest that the family of one-dimensional crystals, including Sb 2 Se 3 , SbSeI and Bi 2 S 3 , show promise in photovoltaic applications.

A facile, environment-friendly, low-cost and time-saving hot-injection process using triethylene glycol as solvent was developed to synthesize uniform and pure-phase Sb 2 Se 3 nanorods with single crystalline structure. The crystal structure, morphology and chemical composition of the synthesized Sb 2 Se 3 nanorods were characterized. The synthesized Sb 2 Se 3 nanorods were used to prepare a photodetector and obtain excellent photoresponsive properties with a switching “on/off” ratio of 70 under 658 nm irradiation (15.8 mW/cm 2 ) at a voltage of 3 V. Moreover, the Sb 2 Se 3 -based photodetector displayed a good durability and fast photoresponsive property with response time of 64 ms and decay time of 68 ms. To our best knowledge, the photoresponsive time of the synthesized Sb 2 Se 3 -based photodetector is faster than that of previous reported Sb 2 Se 3 -based photodetector.

Sb 2 Se 3 is a potential light harvesting material for photovoltaic cells due to its excellent optical, electrical properties and eco-friendly nature. Herein, an efficient Sb 2 Se 3 sensitized solar cell (SSC) is prepared for the first time through a solution-based successive ionic layer adsorption and reaction (SILAR) process which is flexible, low-cost and easy to access. Aiming to further improve the device performance, a novel approach based on TiCl 4 treatment on mesoporous TiO 2 is introduced, which is found to optimize the growth condition of Sb 2 Se 3 nanoparticles and improve the interfacial surface state, resulting in the better band alignment and controlled recombination losses in Sb 2 Se 3 SSCs. The TiCl 4 treated device achieves the better photoelectric conversion efficiency of 1.22%, which is much higher than that of 0.46% for the solar cell without TiCl 4 treatment.

The combination of the SnO 2 and Sb 2 Se 3 offers an alternative strategy for realizing the n-p heterojunction in Sb 2 Se 3 thin-film solar cells. However, the low conductivity of the SnO 2 and the lateral growth of Sb 2 Se 3 grains make carrier extraction more challenging, thereby resulting in unsatisfactory device performance. In this study, the improvement of the Sb 2 Se 3 solar cell performance is achieved by enhancing the conductivity of the SnO 2 and rearranging the Sb 2 Se 3 elongated grains simultaneously so that the carriers can be efficiently transmitted through the grain conduction mode instead of the grain boundary conduction mode. Furthermore, the evolution of (Sb 4 Se 6 ) n ribbons from pure lateral growth to longitudinal growth is observed by adjusting the distribution of doping elements on the SnO 2 surface. Finally, under optimal treatment times, the carrier recombination in the heterojunction is effectively inhibited by building an efficient electron-transport channel, and the Sb 2 Se 3 solar cell achieved the highest power conversion efficiency of 5.41%. Our study clarifies the relationship between carrier transport and grain orientation in one-dimensional Sb 2 Se 3 materials and realized the effective adjustment of the (Sb 4 Se 6 ) n ribbon growth direction. The outcomes of this study provide guidance for the control of carrier behavior in optoelectronic devices with similar one-dimensional absorber materials.

Sb 2 S 3 has emerged as a promising light-absorbing material due to its nontoxicity, low cost, high stability, and absorption coefficient. However, the absorption spectrum ranges and back-contact barrier between Sb 2 S 3 and Au strongly limit the device performance. p-type Sb 2 Se 3 has a similar lattice structure and properties as Sb 2 S 3 , obtaining absorption expansion and ohmic back contact. Herein, efficient all-inorganic planar Sb 2 S 3 solar cells with the addition of Sb 2 Se 3 layers are fabricated. The functions of Sb 2 Se 3 as cooperative absorber (400 nm) and hole transport layers (HTL, 80 nm) are further explored. Systematic characterizations indicate that the junction quality and depletion widths of the device with the addition of Sb 2 Se 3 are improved by forming a p–i–n structure. As a result, the all-inorganic Sb 2 S 3 solar cell with a Sb 2 Se 3 HTL greatly increases the power conversion efficiency from 2.7% to 5.8% and the fill factor from 40% to 55.4%. The additional Sb 2 Se 3 /Au interface with matched energy-level alignments reduces the back-contact barrier and facilitates hole transport and collection. The present design and methods promote the development of Sb 2 S 3 solar cells.

Abstract The strong Ti-O bonds in TiO 2 and poor compatibility with Sb 2 Se 3 result in poor performance when used as electron transport layers (ETL) for Sb 2 Se 3 solar cells. Therefore, cadmium sulfide is usually used as a buffer layer to improve its compatibility. In the present work, we deposited a layer of CdS by spin coating method on TiO 2 ETL and fabricated TiO 2 /CdS dual ETL. The CdS layer improved the electronic properties of TiO 2 and grain orientation of Sb 2 Se 3 thin films. As a result, the average short circuit current and fill factor of Sb 2 Se 3 solar cells were improved, and the final champion power conversion efficiency was enhanced from 2.6% to 4.71%. This study supplied a route for the application of titanium dioxide as a broad band gap electron transfer material for Sb 2 Se 3 solar cells. Graphical Abstract In this work, we deposited a 120 nm CdS layer on TiO 2 ETL. The CdS layer improved the electronic properties of TiO 2 and optimized the grain orientation of Sb 2 Se 3 thin films. The Jsc and Voc of Sb 2 Se 3 solar cells were also improved, and the ultimate champion power conversion efficiency was enhanced from 2.60 to 4.71%. Our work provides an effective method to improve the photovoltaic performance of Sb 2 Se 3 solar cells.

Sb 2 Se 3 with its excellent optical, electrical properties emerging as a promising next-generation light harvesting material has gained immense research interest. However, in the Sb 2 Se 3 photovoltaic devices , the impediment of charge transport within the layered structure dragged down the device performance. Here, for the first time, we reported the air-stabled Sb 2 Se 3 sensitized solar cells (SSCs) modified with CdSe interlayer at the TiO 2 /Sb 2 Se 3 heterojunction through successive ionic layer adsorption and reaction (SILAR) process. CdSe modification provided the reduced TiO 2 work function, enhanced optical absorption and suppressed charge recombination. The short-circuit current density, fill factor and open-circuit voltage of the Sb 2 Se 3 SSCs were all remarkably improved. When CdSe layer with five SILAR cycles was applied, the device power conversion efficiency (PCE) was as high as 1.96%, which was the highest recorded PCE of Sb 2 Se 3 nanoparticle based solar cells. Our work illustrates that interfacial engineering provided a useful route to adjust the interface configuration in Sb 2 Se 3 based solar cell and optoelectronic applications .

Antimony selenide (Sb 2 Se 3 ) is a potential absorber material for environment-friendly and cost-efficient photovoltaics and has achieved considerable progress in recent years. However, the severe open-circuit voltage ( V oc ) deficit ascribed to the interface and/or bulk defect states has become the main obstacle for further efficiency improvement. In this work, Sb 2 Se 3 absorber layer was prepared by an effective combination reaction involving sputtered and selenized Sb precursor thin films . The self-assembled growth of Sb 2 Se 3 thin films with large crystal grains, benign preferential orientation, and accurate chemical composition were successfully fulfilled under an appropriate thickness of Sb precursor and an optimized selenization scenario. Substrate structured Sb 2 Se 3 thin-film solar cells, a champion device with a power-conversion efficiency of 6.84%, were fabricated. This device is comparable to state-of-the-art ones and represents the highest efficiency of sputtered Sb 2 Se 3 solar cells. Importantly, the high V oc of 504 mV is closely related to the reduced deep level defect density for the Sb 2 Se 3 absorber layer, the passivated interfacial defects for Sb 2 Se 3 /CdS heterojunction interface, and the additional heterojunction heat treatment-induced Cd and S inter-diffusion. This significantly improved V oc demonstrates remarkable potential to broaden its scope of applications for Sb 2 Se 3 solar cells.
