Controlling the perovskite morphology and defects at buried perovskite-substrate interface is challenging for inverted solar cells. In this work, we report an amphiphilic molecular hole transporter, (2-(4-(bis(4-methoxyphenyl)amino)phenyl)-1-cyanovinyl)phosphonic acid, that features a multifunctional cyanovinyl phosphonic acid group forms superwetting underlayer deposition, which enables high-quality films with minimized interface. The resulting film has photoluminescence quantum yield of...
Abstract The commonly-used superstrate configuration (depositing front subcell first and then depositing back subcell) in all-perovskite tandem solar cells is disadvantageous for long-term stability due to oxidizable narrow-bandgap perovskite assembled last easily exposable air. Here we reverse the processing order demonstrate tandems a substrate bury deep device stack. By using guanidinium tetrafluoroborate additive wide-bandgap subcell, achieve an efficiency of 25.3% substrate-configured...
Abstract Moiré superlattices formed by twisted stacking in van der Waals materials have emerged as a new platform for exploring the physics of strongly correlated and other emergent phenomena 1–5 . However, there remains lack research on mechanical properties twisted-layer materials, owing to suitable strategies making three-dimensional bulk materials. Here we report successful synthesis polycrystalline boron nitride ceramic with high room-temperature deformability strength. This ceramic,...
In this paper, we propose a Timed Efficient and Secure Vehicular Communication (TSVC) scheme with privacy preservation, which aims at minimizing the packet overhead in terms of signature verification latency without compromising security requirements. Compared currently existing public key based authentication schemes for privacy, communication computation TSVC can be significantly reduced due to short message code (MAC) tag attached each authentication, by only fast hash operation is...
The ability to sense heat and touch is essential for healthcare, robotics, human–machine interfaces. By taking advantage of the engineerable waveguiding properties, we design fabricate a flexible optical microfiber sensor simultaneous temperature pressure measurement based on theoretical calculation. exhibits high sensitivity 1.2 nm/°C by measuring shift high-order mode cutoff wavelength in short-wavelength range. In case sensing, shows 4.5% per kilopascal with fast temporal frequency...
Halide diffusion across the charge-transporting layer followed by a reaction with metal electrode represents critical factor limiting long-term stability of perovskite solar cells (PSCs). In this work, supramolecular strategy surface anion complexation is reported for enhancing light and thermal films, as well devices. Calix[4]pyrrole (C[4]P) demonstrated unique anion-binding agent stabilizing structure anchoring halides, which increases activation energy halide migration, thus effectively...
Abstract This article presents detailed structural, electronic, magnetic, and thermoelectric properties of two experimentally existing isostructural variant perovskite compounds Tl 2 NbX 6 (X = Cl, Br) with the help first principles calculations. As per requirement stability in device applications, structural thermodynamic stabilities were, respectively verified by tolerance factor negative formation energies. The parameters ferromagnetic phase were calculated found close agreement available...
Abstract Low-dimensional hybrid perovskites have demonstrated excellent performance as white-light emitters. The broadband white emission originates from self-trapped excitons (STEs). Since the mechanism of STEs formation in is still not clear, preparing new low-dimensional relies mostly on screening lots intercalated organic molecules rather than rational design. Here, we report an atom-substituting strategy to trigger layered perovskites. Halogen-substituted phenyl are applied synthesize...
The current reported wide band gap perovskites based on iodide–bromine mixed halide composition would suffer from segregation. Here, we Cs-rich pure-iodide CsxFA1–x–yDMAyPbI3 (x > 0.5; y < 0.01) (denoted as CsFA) and successfully solved the problem of phase segregation in perovskites. comprehensive experimental theoretical results indicated that, because a mildly deformed octahedral framework, our fabricated CsFA exhibit much higher stability than those with similar gaps under thermal or...
Myocardial infarction (MI) is a typical cardiovascular disease, causing disability and death worldwide. Exosomes secreted by mesenchymal stem cells (MSCs) showed remarkable therapeutic effects in MI restoring cardiac function. However, the application of exosomes remains challenge because their low residence rate infarcted myocardium. Herein, fibrin-based patch was prepared to deliver MSCs-derived heart using an mouse model, aiming at improvement functions. The fibrin optimized for size...
Metal halide perovskite light-emitting diodes (LEDs) have achieved great progress in recent years. However, bright and spectrally stable blue LED remains a significant challenge. Three-dimensional mixed-halide perovskites potential to achieve high brightness electroluminescence, but their emission spectra are unstable as result of phase separation. Here, we reveal that there is already heterogeneous distribution halides the as-deposited films, which can trace back nonuniform mixture...
