A redox road to recovery Device longevity is a key issue for organic-inorganic perovskite solar cells. Encapsulation can limit degradation arising from reactions with oxygen and water, but light, electric-field, thermal stresses lead metastable elemental halide atom defects. Wang et al. show that the lead-iodine system, introduction of rare earth europium ion pair Eu 3+ -Eu 2+ shuttle electrons recover iodine ions (Pb I − ). Devices incorporating this maintained more than 90% their initial...
Abstract Further minimizing the defect state density in semiconducting absorber is vital to boost power conversion efficiency of solar cells approaching Shockley-Queisser limit. However, it lacks a general strategy control precursor chemistry for defects reduction family iodine based perovskite. Here alkaline environment solution carefully investigated as an effective parameter suppress incident and affects crystallization kinetics during film fabrication, via rationale adjustment alkalinity...
Engineering the chemical composition of organic and inorganic hybrid perovskite materials is one most feasible methods to boost efficiency solar cells with improved device stability. Among diverse family ABX3, formamidinium (FA)-based mixed (e.g., FA1−xCsxPbI3) possesses optimum bandgaps, superior optoelectronic property, as well thermal- photostability, which proven be promising candidate for advanced cell. Here, FA0.9Cs0.1PbI3(Cl) implemented light-harvesting layer in planar devices,...
Crystal orientation has a great impact on the properties of perovskite films and resultant device performance. Up to now, exquisite control crystal (the preferred crystallographic planes stacking mode with respect particular planes) in mixed-cation perovskites received limited success, underlying mechanism that governs performance is still not clear. Here, thermodynamically favored formamidinium/methylammonium (FA/MA) finely tuned by composition engineering. Density functional theory...
In this study, an electrochemiluminescence (ECL) regenerated biosensor was reported to sensitively detect microRNA through 3D DNA walking machine and "on–off–super on" strategy. First, with higher efficiency of payload releasing superior signal amplification than those the traditional initially introduced in ECL system for converting target intermediate achieving significant amplification. Second, distance between CdS:Mn quantum dots Au nanoparticles increased hybridization modified S2,...
Recently, perovskite/Si devices have attracted enormous interest as an ideal technology for tandem cells, particularly due to the attributes from perovskite cell including low temperature processibility, tunable optical bandgap, and high open circuit voltage. Although solution process is considered be cost effective more widely adoptable subcell, best of our knowledge, there has been no successful demonstration resulting performance two‐terminal cells. In this manuscript, employed fabricate...
Refractory high-entropy alloys (RHEAs) are promising materials used at high temperature, but their low plasticity restricts application. Based on the valence electron concentration (VEC) principle, four kinds of RHEAs (ZrTiHfV
A hybrid perovskite memory device with a decent set voltage has been successfully demonstrated, and the performance was correlated to defect density hysteresis-index of different films.
Intelligent DNA walking machines have become a great hot spot in biosensing, but the efficiency of was still limited due to low local concentration substance and derail leg DNA. Herein, Zn2+-driven rolling machine proposed overcome above shortages applied as electrochemiluminescence (ECL) biosensor for speedy ultrasensitive detection microRNA-21. First, original synthesized by numbers modified on Au nanoparticle which matched with high track sensing platform could roll efficiently through...
Developing low cost and stable metal electrode is crucial for mass production of perovskite solar cells (PSCs). As an earth-abundant element, Cu becomes alternative candidate to replace noble electrodes such as Au Ag, due its comparable physiochemical properties with simultaneously good stability cost. However, the undesirable band alignment associated device architecture impedes exploration efficient Cu-based n-i-p PSCs. Here, we demonstrated ability tuning Fermi level ( <mml:math...

Here we report intensive exploration mixed-cation in their compositional space with assistance a rational mixture design (MD) methods. Different from previous linear search cation ratios, it...
We introduced hydrophobic P4VP to substantially reduce the undesired HTL pinholes in temporal and spatial perspectives for more stable PSCs.
Abstract Endothelial senescence is believed to constitute the initial pathogenesis of atherosclerotic cardiovascular disease (ASCVD). MicroRNA-335-5p (miR-335-5p) expression significantly up-regulated in oxidative stress-induced endothelial cells (ECs). Sirtuin7 (SIRT7) considered prevent EC senescence, yet data on its response ASCVD risk factors are limited. The present study analyzed elevated levels miR-335-5p and decreased SIRT7 human umbilical vein (HUVECs), found that high glucose,...
Delivery of CRISPR/Cas9 ribonucleoproteins (RNPs) offers a powerful tool for therapeutic genome editing.
