Incorporating mixed ion is a frequently used strategy to stabilize black-phase formamidinum lead iodide perovskite for high-efficiency solar cells. However, these devices commonly suffer from photoinduced phase segregation and humidity instability. Herein, we find that the underlying reason halide perovskites generally fail grow into homogenous high-crystalline film, due multiple pathways of crystal nucleation originating various intermediate phases in film-forming process. Therefore, design...
Abstract Recently, organic–inorganic metal halide perovskite solar cells (PSCs) have achieved rapid improvement, however, the efficiencies are still behind Shockley–Queisser theory mainly due to their high energy loss ( E LOSS ) in open‐circuit voltage V OC ). Due polycrystalline nature of solution‐prepared films, defects at grain boundaries as non‐radiative recombination centers greatly affect and limit device efficiency. Herein, poly(vinylidene fluoride) (PVDF) is introduced...
Abstract Interfacial engineering of perovskite films has been the main strategies in improving efficiency and stability solar cells (PSCs). In this study, three new donor‐acceptor (D–A)‐type interfacial dipole (DAID) molecules with hole‐transporting different anchoring units are designed employed PSCs. The formation interface dipoles by DAID on film can efficiently modulate energy level alignment, improve charge extraction, reduce non‐radiative recombination. Among molecules, TPA‐BAM amide...
Keyhole instability during laser welding and powder bed fusion (LPBF) can cause keyhole collapse pore formation. Using high-speed x-ray imaging, we demonstrate that the flow vortex-induced protrusion on rear wall is crucial in initiating instability. Applying a transverse magnetic field suppresses by driving secondary thermoelectric magnetohydrodynamics (TEMHD) alters net vortex. This minimizes protrusions large-amplitude oscillations. The suppression effectiveness depends scanning direction...
Maize (Zea mays) is a major staple crop. kernel size and weight are important contributors to its yield. Here, we measured length, width, thickness, hundred weight, test in 10 recombinant inbred line populations dissected their genetic architecture using three statistical models. In total, 729 quantitative trait loci (QTLs) were identified, many of which identified all models, including 22 QTLs that each can explain more than 10% phenotypic variation. To provide candidate genes for these...
A blue diode laser has a higher absorption rate than traditional laser, while the maximum power is limited. We report structure and beam profile of 250 W high-power (445 nm) for material processing. The system steel was 2.75 times that single-mode fiber (1070 nm). characteristics after irradiation were determined, validating potential this processing, such as heat treatment cladding. cost developed lower existing one. To best our knowledge, first with high W.
In-situ pre-decorated different content of TiB2 particle reinforced 2024 Al matrix composites (xTiB2/2024Al composite, x = 0, 1, 2, 4, 6, 8 wt.%) were printed by laser powder bed fusion (LPBF). A quantitative equation was established to quantify heterogeneous nucleating potency nanoparticles on the grain size LPBFed samples. Optimized mechanical properties obtained in as-printed 4TiB2/2024Al alloy which proved feasibility replacing wrought part with one. This manuscript provides a method...
Although the power conversion efficiency values of perovskite solar cells continue to be refreshed, it is still far from theoretical Shockley-Queisser limit. Two major issues need addressed, including disorder crystallization and unbalanced interface charge extraction, which limit further improvements in device efficiency. Herein, we develop a thermally polymerized additive as polymer template film, can form monolithic grain unique "Mortise-Tenon" structure after spin-coating hole-transport...
The fracture behaviour of artificial metamaterials often leads to catastrophic failures with limited resistance crack propagation. In contrast, natural materials such as bones and ceramics possess microstructures that give rise spatially controllable path toughened material advances. This study presents an approach is inspired by nature's strengthening mechanisms develop a systematic design method enabling damage-programmable engineerable microfibers in the cells can program micro-scale...
The circular economy (CE) aims to decouple the growth of from consumption finite resources through strategies, such as eliminating waste, circulating materials in use, and regenerating natural systems. Due rapid development data science (DS), promising progress has been made transition toward CE past decade. DS offers various methods achieve accurate predictions, accelerate product sustainable design, prolong asset life, optimize infrastructure needed circulate materials, provide...
