    Wiley
    AbstractThe utilization of small organic molecules with appropriate functional groups and geometric configurations for surface passivation is essential for achieving efficient and stable perovskite solar cells (PSCs). In this study, two isomers, 4‐sulfonamidobenzoic acid (4‐SA) and 3‐sulfamobenzoic acid (3‐SA), both featuring sulfanilamide and carboxyl functional groups arranged in different positions, are evaluated for their effectiveness in passivating defects of the perovskite layer. The calculation and characterization results reveal that 3‐SA, with its meta‐substitution, offered superior passivation compared to the para‐substituted 4‐SA, leading to enhanced charge carrier dynamics and extraction efficiency. The devices treated with 3‐SA demonstrates a notable increase in power conversion efficiency from 21.50% to 23.30%. Moreover, these devices maintain over 90% of their initial efficiency after 2000 h in a 30% relative humidity environment, showcasing exceptional long‐term stability. This research advances strategic design approaches for small molecule passivation, providing critical insights for the enhancement of perovskite optoelectronic applications.

  • Tailoring efficient manganese bromide-based scintillator films with ethyl acetate assistance
    Kun Zhou, Muhammad Bilal, Kaiyu Xia, Yuting Xie, Ting Chen, Xiaofeng Hu, Xiuyuan Chen, Chenchen Yang, Shicheng Pan, Gang Xu,et al.
    IOP Publishing
    Abstract Metal halide (MH) scintillators serve as a compelling substitute for traditional scintillators in x-ray detection and imaging due to their low-temperature fabrication process, high light yield and mechanical flexibility. Nevertheless, the spatial resolution and photoluminescence quantum yield (PLQY) of these films are hindered by the agglomeration and uneven distribution of MHs crystal particles during the fabrication process. We introduce a modified fabrication approach for MH scintillator films involving an additional step of ethyl acetate (EA) treatment, resulting in the preparation of a smooth EA-treated (Ph4P)2MnBr4/Polydimethylsiloxane film (Ph4P = Tetraphenylphosphonium). The carbonyl groups within EA interact with elements of the (Ph4P)2MnBr4 microcrystals powder, ensuring uniform dispersion and preventing agglomeration. The EA-treated composite film demonstrates a remarkable PLQY of approximately 95.8% and an impressive spatial resolution of 14 lp mm−1, with enhanced stability under harsh environments. These characteristics ensure its suitability as a high-performance x-ray imaging scintillator.

    A new passivator, 4-aminophenyl sulfone (APS), containing a Lewis base group (SO), could interact with the uncoordinated Pb2+ on perovskite surface, which not only reduces trap state density but also induces a more p-type surface of perovskite film.

  • Multifunctional Flexible AgNW/MXene/PDMS Composite Films for Efficient Electromagnetic Interference Shielding and Strain Sensing
    Xiaolong Bian, Zhonglin Yang, Tao Zhang, Jiewen Yu, Gaopeng Xu, An Chen, Qingquan He, and Jun Pan
    American Chemical Society (ACS)
    With the rapid development of electronic information technology, composite materials with outstanding performance in terms of electromagnetic interference (EMI) shielding and strain sensing are crucial for next-generation smart wearable electronic devices. However, the fabrication of flexible composite films with dual functionality remains a significant challenge. Herein, multifunctional flexible composite films with exciting EMI shielding and strain sensing properties were constructed using a facile vacuum-assisted filtration process and transfer method. The films consisted of ultrathin AgNW/MXene (Ti3C2Tx)/AgNW conductive networks (1 μm) attached to a flexible polydimethylsiloxane (PDMS) substrate. The obtained AgNW/MXene/PDMS composite film exhibited an exceptional EMI shielding effectiveness of 50.82 dB and good flexibility (retaining 93.67 and 90.18% of its original value after 1000 bending and stretching cycles, respectively), which are attributed to the enhanced multilayer internal reflection network created by the AgNWs and MXene as well as the synergistic effect of PDMS. Besides EMI shielding, the composite films also displayed remarkable strain sensing properties. They exhibited a wide linear range of tensile strain up to 68% with a gauge factor of 468. They also showed fast response, ultralow detection limit, and high mechanical stability. Interestingly, the composite films could also detect motion and voice recognition, demonstrating their potential as wearable sensors. This study highlights the effectiveness of multifunctional flexible AgNW/MXene/PDMS composite films in resisting electromagnetic radiation and monitoring human motion, thereby providing a promising solution for the development of flexible wearable electronic devices in complex electromagnetic environments.

  • In situ growth strategy to construct perovskite quantum dot@covalent organic framework composites with enhanced water stability
    Hongyan Zhang, Xiaoxiong He, Hao Wang, Liangjun Chen, Gaopeng Xu, Nan Zhang, Kang Qu, Qingquan He, Yongwu Peng, and Jun Pan
    IOP Publishing
    Abstract Metal halide perovskite quantum dots (QDs) have excellent optoelectronic properties; however, their poor stability under water or thermal conditions remains an obstacle to commercialization. Here, we used a carboxyl functional group (−COOH) to enhance the ability of a covalent organic framework (COF) to adsorb lead ions and grow CH3NH3PbBr3 (MAPbBr3) QDs in situ into a mesoporous carboxyl-functionalized COF to construct MAPbBr3 QDs@COF core–shell-like composites to improve the stability of perovskites. Owing to the protection of the COF, the as-prepared composites exhibited enhanced water stability, and the characteristic fluorescence was maintained for more than 15 d. These MAPbBr3 QDs@COF composites can be used to fabricate white light-emitting diodes with a color comparable to natural white emission. This work demonstrates the importance of functional groups for the in situ growth of perovskite QDs, and coating with a porous structure is an effective way to improve the stability of metal halide perovskites.

    Metal halide perovskites are promising energy materials because of their high absorption coefficients, long carrier lifetimes, strong photoluminescence, and low cost. Low-dimensional halide perovskites, especially one-dimensional (1D) halide perovskite nanowires (NWs), have become a hot research topic in optoelectronics owing to their excellent optoelectronic properties. Herein, we review the synthetic strategies and mechanisms of halide perovskite NWs in recent years, such as hot injection, vapor phase growth, selfassembly, and solvothermal synthesis. Furthermore, we summarize their applications in optoelectronics, including lasers, photodetectors, and solar cells. Finally, we propose possible perspectives for the development of halide perovskite NWs.

    American Chemical Society (ACS)
    Metal halide perovskites possess many physical properties amenable to optoelectronic applications, whereas the realization of these potentials has been hampered by their environmental and electronic instabilities. The morphological and molecular low dimensional perovskites and perovskite related materials have shown much promise in enhancing the chemical stability due to their unique molecular structures. Here we report on robust and reproducible four-terminal (4T) electrical measurements in a one-dimensional (1D) organic metal halide hybrid, (R)-α-methylbenzylammonium lead triiodide ((R-α-MBA)PbI 3 ) made possible by its chemical stability. The results reveal a distinct intrinsic ion migration dynamic of single exponential, which underlies the unique 4T I-V characteristics. The dynamic is directly verified by real-time measurements of the transient ionic current. Our observations are consistent with photo-activation and field-assisted ion migration. The elucidated intrinsic ion dynamics may provide the physical basis for understanding and modelling the ubiquitous hysteresis in metal halides based electronic devices and new insights into the dynamics of ion migration in metal halide perovskites and hybrids in general.

  • Remarkable quality improvement of CsPbIBr<inf>2</inf> perovskite film by cellulose acetate addition for efficient and stable carbon-based inorganic perovskite solar cells
    Jieqiong Liu, Qingquan He, Jiayu Bi, Miao Lei, Wei Zhang, and Guiqiang Wang
    Elsevier BV
    Abstract All-inorganic CsPbIBr2 perovskite has been regarded as a promising candidate for perovskite solar cells (PSCs) considering its suitable bandgap and high stability. However, the poor quality of CsPbIBr2 film greatly impedes the performance improvement of CsPbIBr2-based PSCs. Herein, we report a facile strategy to improve the quality of CsPbIBr2 perovskite film by introducing cellulose acetate (CA) into the perovskite precursor solution. The interaction between the oxygen functional groups of CA and Pb2+ and the increase of the precursor viscosity induced by CA addition can slow down the crystallization rate of CsPbIBr2 perovskite, which allows the perovskite films have enough time to form high-quality crystal structure. By optimizing the amount of CA (the optimal amount of CA is 2.5 wt%), a high-quality CsPbIBr2 perovskite film with high crystallinity, large grain size, and smooth surface is obtained. As consequence, the carbon-based PSC with a structure of FTO/TiO2/perovskite/carbon using the CsPbIBr2 perovskite film with 2.5 wt% CA achieves a champion efficiency of 7.52%, which is increased by 40.8% compared with the cell based on pure CsPbIBr2 perovskite film. In addition, the PSC based on CsPbIBr2 film with CA exhibits an excellent long-term stability under both ambient condition and high-humidity environment.

    Abstract Electrochemical splitting of water is one of the most reliable and effective ways for the sustainable production of pure hydrogen on a large scale, while the core of this technology lies in the development of highly active non-noble-metal-based electrocatalysts to lower the large dynamic overpotentials of electrode materials. Here, an interface engineering strategy is demonstrated to construct an efficient and stable catalyst based on NiS@MoS2 core-shell hierarchical microspheres for the hydrogen evolution reactions (HER). The ultrathin MoS2 nanosheets in-situ grow on the surface of NiS hierarchical micro-sized spheres constructed by porous nanoplates, endowing the composites with rich interfaces, well-exposed electroactive edges, high structural porosity and fast transport channels. These advantages are favorable for the improvement of catalytic sites and the transport of catalysis-relevant species. More importantly, the intimate contact between MoS2 nanosheets and NiS nanoplates synergistically favors the chemical sorption of hydrogen intermediates, thereby reducing the reaction barrier and accelerating the HER catalytic process. As a result, the optimized NiS@MoS2 catalyst manifests impressive HER activity and durability, with a low overpotential of 208 mV in 0.5 M H2SO4 and 146 mV in 1.0 M KOH at 10 mA cm−2, respectively. This work not only provides an effective way to construct core-shell hierarchical microspheres but also a multiscale strategy to regulate the electronic structure of heterostructured materials for energy-related applications.

    Surface passivation of perovskite thin films has been established as a promising approach to improving both the efficiency and stability of perovskite solar cells (PSCs). While remarkable progress has been achieved with various surface passivating agents, long-term stability of PSCs has not been fully addressed. Here, we report a new strategy for surface passivation of PSCs using a low cost industrial organic pigment quinacridone (QA). The procedure involves solution processing a soluble derivative of QA, N,N-bis(tert-butyloxycarbonyl)-quinacridone (TBOC-QA), followed by facile thermal annealing to convert TBOC-QA to insoluble QA. With the halide perovskite thin films coated by QA, PSCs based on methylammonium lead Iodide (MAPbI3) showed significantly improved performance with remarkable stability. A PCE of 21.1% was achieved, which is much higher than 18.9% recorded for the unmodified devices. Density functional theory calculations revealed strong interactions between QA molecules and metal halides, which effectively reduced the surface defects of halide perovskite thin films and suppressed the nonradiative recombination. The QA coating with exceptional insolubility and hydrophobicity also led to remarkably enhanced contact angle from 35.6⁰ for the pristine MAPbI3 thin films to 77.2⁰ for QA coated MAPbI3 thin films. As a result, the stabilities of QA passivated MAPbI3 perovskite thin films and PSCs were greatly enhanced, retaining about 90 % of the initial efficiencies after more than 1000 hours storage under ambient conditions. The universality of this passivation strategy was evaluated by extending MAPbI3 systems to triple-cation mixed-halide perovskite systems, which further confirm the effectiveness of industrial pigment passivation of PSCs with enhanced efficiency and stability.

  • Metal Halide Regulated Photophysical Tuning of Zero-Dimensional Organic Metal Halide Hybrids: From Efficient Phosphorescence to Ultralong Afterglow

    Wiley
    Zero-dimensional (0D) organic metal halide hybrids have emerged as a new class of luminescent materials with exceptional structural and photophysical tunability, thanks to the rich choices of organic cations and metal halides for the formation of ionically bonded systems. Here we report photophysical tuning of a series of tetraphenylphosphonium (TPP) metal halide hybrids containing distinct metal halides, TPP 2 MX n (MX n = SbCl 5 , MnCl 4 , ZnCl 4 , ZnCl 2 Br 2 , ZnBr 4 ), from efficient phosphorescence to ultralong afterglow. It is found that the afterglow properties of TPP + cations could be suspended for the hybrids containing low bandgap emissive metal halide species, such as SbCl 5 2- and MnCl 4 2- , but significantly enhanced for the hybrids containing wide bandgap non-emissive ZnCl 4 2- . Structural and photophysical studies reveal that the enhanced afterglow is attributed to stronger π - π stacking and intermolecular electronic coupling between TPP + cations in TPP 2 ZnCl 4 than in the pristine organic ionic compound TPPCl. Moreover, the afterglow in TPP 2 ZnX 4 can be tuned by controlling the halide composition, with the change from Cl to Br resulting in a shorter afterglow due to heavy atom effect.

    Springer Science and Business Media LLC
    AbstractScintillation based X-ray detection has received great attention for its application in a wide range of areas from security to healthcare. Here, we report highly efficient X-ray scintillators with state-of-the-art performance based on an organic metal halide, ethylenebis-triphenylphosphonium manganese (II) bromide ((C38H34P2)MnBr4), which can be prepared using a facile solution growth method at room temperature to form inch sized single crystals. This zero-dimensional organic metal halide hybrid exhibits green emission peaked at 517 nm with a photoluminescence quantum efficiency of ~ 95%. Its X-ray scintillation properties are characterized with an excellent linear response to X-ray dose rate, a high light yield of ~ 80,000 photon MeV−1, and a low detection limit of 72.8 nGy s−1. X-ray imaging tests show that scintillators based on (C38H34P2)MnBr4 powders provide an excellent visualization tool for X-ray radiography, and high resolution flexible scintillators can be fabricated by blending (C38H34P2)MnBr4 powders with polydimethylsiloxane.
