Recently, surface passivation has been proved to be an essential approach for obtaining efficient and stable perovskite light-emitting diodes (Pero-LEDs). Phosphine oxides performed well as passivators in many reports. However, the most commonly used phosphine are insulators, which may inhibit carrier transport between emitter charge-transporter layers, limiting corresponding device performance. Here, 2,7-bis(diphenylphosphoryl)-9,9'-spirobifluorene (SPPO13), a conductive molecule with two...
Constructing 2D/3D perovskite heterojunctions is effective for the surface passivation of solar cells (PSCs). However, previous reports that studying post-treatment only physically deposits 2D on 3D perovskite, and bulk remains defective. Herein, we propose Cl2-dissolved chloroform as a multifunctional solvent concurrently constructing heterojunction inducing secondary growth grains. The mechanism how Cl2 affects performance PSCs clarified. Specifically, dissolved reacts with leading to Cl/I...
All-inorganic and lead-free CsSnI3 is emerging as one of the most promising candidates for near-infrared perovskite light-emitting diodes (NIR Pero-LEDs), which find practical applications including facial recognition, biomedical apparatus, night vision camera, Light Fidelity. However, in -based Pero-LEDs, holes injection significantly higher than that electrons, resulting unbalanced charge injection, undesired exciton dissipation, poor device performance. Herein, it proposed to manage...
Nontoxic Sn-based perovskite light-emitting diodes (Pero-LEDs) have been developing rapidly in recent years. However, high-quality films are hardly prepared because of the heavy self-doping Sn4+ as-prepared films. Most previous reports indicate that formation is mainly attributed to Sn2+ oxidation by external oxidizers. Here, for first time, we reveal disproportionation decomposition during annealing process plays a critical role degrading device performance. To resolve this issue,...
The modification of perovskite precursor by a series phosphoryl chloride molecules can indeed improve the performance LEDs (Pero-LEDs). bis(2-oxo-3-oxazolidinyl) phosphinic not only regulate phase distribution controlling crystallization rate but also passivate defects quasi-2D perovskite. Highly efficient and reproducible Pero-LEDs are achieved with an maximum external quantum efficiency (EQEmax) 20.82% average EQE (EQEave) around 20% on 50 devices. Quasi-2D perovskites have attracted...
In this Letter, a delta-sigma modulation (DSM) encryption technique in W-band RoF system is proposed. By performing DSM with different over-sample ratios (OSRs) on the OFDM signal based controlled keys generated by chaotic at transmitter and constellation masking to disturb transmitting for encryption, high-order QAM-OFDM-DSM encrypted achieved. order further improve security of system, bit bidirectional diffusion scrambling used resist chosen-plaintext attacks. After experimental...
Layered cathodes have been recognized as potential advanced candidates for sodium-ion batteries (SIBs), but the poor electrochemical performance has seriously hindered their further development. Herein, an ordered Na2/3[Ni2/9Mg1/9Mn5/9Ti1/9]O2 (NMMT) is designed and investigated a high-performance cathode SIBs through synergistic effect of Mg Ti codoping. Compared to single Mg- or Ti-doped materials, NMMT clearly exhibits superstructure ordering diffraction peaks, neutron confirms that peaks...
Abstract Recently, lead‐free Sn‐based perovskite light‐emitting diodes (PeLEDs) have attracted wide attention due to their near‐infrared emission and environmental friendliness. However, desired Sn 2+ is easily oxidized 4+ in the crystallization process, resulting defects intrinsically p‐doped properties films. The uncontrollable oxidation affects charge injection balance radiative recombination, leading poor device performance. Herein, a bi‐functional conductive molecular,...
Exploiting high-performance cathodes is still in need for sodium-ion batteries, which critical to promote their commercialization. Layered sodium manganese oxide show low cost and natural abundance but suffer from poor cycling life rate capacity. Herein, electrochemically inert Ti4+ active Ni2+ are used replace some Mn ions Na0.62MnO2, neutron power diffraction results demonstrate a negligible change the sizes of metal layer Na-ion structure. Although Na0.62[Ni0.12Ti0.12Mn0.76]O2 Na0.62MnO2...
Abstract Metal halide perovskite light‐emitting diodes (Pero‐LEDs) have gained great attention due to their promising applications in lighting and displays. However, conventional three‐layered sandwich structure, some undeserved carrier behaviors, such as imbalanced injection, severe loss, unstable recombination zone, limit the device's performance. Herein, a four‐layered design by inserting nickel acetate (Ni(OAc) 2 ) interlayer between emitter hole‐transport layer(HTL) manage behavior...
Designing high-performance layered cathodes, in particular the P2-type groups, is still challenging for sodium-ion batteries. Taking advantage of well-known Li/Ni mixing Ni-rich cathodes Li-ion batteries, a Na2/3Li1/9[Ni2/9Li1/9Mn2/3]O2 cathode with superior rate and long-cycle performance developed through incorporation. Neutron diffraction indicates that introduced Li ions occupy intrinsic Na+ vacancies Na layer transition metal concurrently. A facile solid-solution reaction mechanism upon...
Effects of chlorination on photovoltaic performance organic solar cells are yet largely unclear though it is emerging as a special effective strategy to design highly efficient non-fullerene acceptors (NFAs). Herein, bi-chlorine-substituted NFA with regioregularity, namely, bichlorinated dithienothiophen[3.2-b]- pyrrolobenzothiadiazole (BTP-2Cl-δ), synthesized and compared the non-chlorinated BTP tetra-chlorine-substituted BTP-4Cl study effects Cl number performance. From BTP-2Cl-δ BTP-4Cl,...
Practical applications of CsPbX3 nanocrystals (NCs) are limited by their poor stability. The formation a heterojunction between NCs and oxides is an effective means to protect perovskite from polar solvents other external factors. Significantly improving the stability photocatalytic properties core/shell very important for its application in photoelectric technology. Here, we report synthesis asymmetrical CsPbBr3/TiO2 core–shell heterostructure at single-particle level hot-injection...
