Perovskite synthesis out in the open Although methods have been developed that create photoactive black perovskite phase of formamidinium lead iodide (α-FAPbI 3 ), these routes are temperature and humidity sensitive less compatible with large-scale solar cell production. Hui et al. report an alternative route which vertically aligned thin films grown from ionic liquid methylamine formate. Nanoscale channels lower barrier to permeation enable transformation α-FAPbI , even at high room...
Dropout is a powerful and widely used technique to regularize the training of deep neural networks. In this paper, we introduce simple regularization strategy upon dropout in model training, namely R-Drop, which forces output distributions different sub models generated by be consistent with each other. Specifically, for sample, R-Drop minimizes bidirectional KL-divergence between two sampled dropout. Theoretical analysis reveals that reduces freedom parameters complements Experiments on...

Initiated chemical vapor deposition (iCVD) is a versatile technique that enables the direct growth of nanostructures and surface modification such structures. Unlike traditional CVD methods, iCVD operates under mild conditions, allowing for damage-free processing delicate substrates. It can produce highly uniform polymer layers, with thicknesses ranging from over 15 μm to sub-10 nm, conformally coating intricate geometries. The broad range compositions achievable offers precise control...
Photodetectors based on three dimensional organic-inorganic lead halide perovskites have recently received significant attention. As a new type of light-harvesting materials, formamidinium iodide (FAPbI3) is known to possess excellent optoelectronic properties even exceeding those methylammonium (MAPbI3). To date, only few photoconductor-type photodetectors FAPbI3 single crystals and polycrystalline thin films in lateral structure been reported. Here, we demonstrate low-voltage,...
Organic–inorganic halide perovskites have attracted enormous attention for future optoelectronic applications because of their remarkable optical and electrical properties, solution processability, low cost, large-scale fabrication capabilities. In addition to use in photovoltaics light-emitting diodes, recently emerged as promising candidates new-generation photodetectors. However, conventional three-dimensional perovskite photodetectors suffer from current–voltage hysteresis, unreliable...
Electron-transport-layer free perovskite solar cells (ETL-free PSCs) have attracted great attention due to their low cost and simple manufacturing process. However, an additional interface layer has be introduced, the currently achieved efficiency remains far from full-structure PSCs. Here, we report in situ engineering strategy by methylammonium acetate (MAAc) ionic liquid precursor. We found that a dipole was constructed through physical adsorption of residual MAAc polar molecules on...

Most organic photodetectors utilize a bulk heterojunction (BHJ) photo-active film due to its high exciton dissociation efficiency. However, the low dark current density, key role in determining overall performance of photodetectors, is hardly achieved BHJ structure since both donor and acceptor domains are contact with same electrode. The most popular strategy overcome this problem by fabricating bilayer or multilayer devices. complicated fabrication process challenge for printing...
