Minimizing energy loss is of critical importance in the pursuit attaining high-performance organic solar cells. Interestingly, reorganization plays a crucial role photoelectric conversion processes. However, understanding relationship between and losses has rarely been studied. Here, two acceptors, Qx-1 Qx-2, were developed. The energies these acceptors during processes are substantially smaller than conventional Y6 acceptor, which beneficial for improving exciton lifetime diffusion length,...
Slot-die coating is recognized as the most compatible method for roll-to-roll (R2R) processing of large-area flexible organic solar cells (OSCs). However, photovoltaic performance OSC lags significantly behind that traditional spin-coating devices. In this work, two acceptors, Qx-1 and Qx-2, show quite different film-formation kinetics in slot-die process. situ absorption spectroscopy indicates excessive crystallinity Qx-2 provides early phase separation aggregation, resulting oversized...
Abstract The relatively large non‐radiative recombination energy loss (Δ E 3 ) is the main source of losses in organic solar cells (OSCs). energetic disorder plays a crucial role losses; however, reducing by modifying terminal groups has rarely been investigated. Herein, four acceptors, BTP‐ICB1F, BTP‐ICB2F, BTP‐ICB3F, and BTP‐ICBCF3, with fluorinated phenyl are reported at identified substitution sites. theoretical experimental results show that this system possesses smaller than...
Siloxane with low surface tension can regulate the intermolecular interactions, and optimize phase separation morphology molecule stacking, finally contributing to an excellent PCE of 16.4% small energy loss for ASM-OSCs.
Abstract The commercialization of organic solar cells (OSCs) requires the use roll‐to‐roll coating technology. However, it is generally believed that all‐small‐molecule (ASM) systems cannot form high‐quality films in most film‐fabrication technologies except for spin coating, mainly due to their strong crystallinity and low solution viscosity. Herein, found small molecule donor acceptor system with intermolecular interaction can weaken molecular self‐aggregation during film formation. As a...
Abstract The optimization of bulk heterojunction morphology is one the most challenging topics in all‐small‐molecule organic solar cells. Herein, three small molecular donors based on dithieno[2,3‐d;2′,3′‐d′]benzo[1,2‐b;4,5‐b′]dithiophene (DTBDT) unit by systematically moving branching point alkyl chain have been designed, synthesized, and applied Modifying points enables properties aggregation state to be tuned, an efficient nanofiber‐based hierarchical successfully demonstrated combining...
Abstract Compared with nonfullerene‐based polymer solar cells, all‐small‐molecule cells normally show low power conversion efficiencies (PCEs) due to their fill factors (FFs). Molecular stacking orientation and phase separation are the main affecting performance of cells. In this work, two liquid‐crystalline small‐molecule donors designed synthesized a novel nonfullerene acceptor good crystallinity developed. Owing face‐on component molecules appropriate in active layer, high FF over 70% PCE...
Covalent organic frameworks (COFs) have emerged as a fascinating crystalline porous material and are widely used in the field of catalysis. However, developing simple approaches to fabricate conjugated COFs with specific functional groups remains significant challenge. In this study, construction defective COF-LZU1 Lewis acid sites embedded into is fulfilled by facile solvent-assisted ligand exchange method. A monodentate ligand, protocatechualdehyde, successfully introduced skeleton...

Charge carrier light managements important to optimize NFA molecules. Herein, four NFAs with different alkyl substituents end groups, named BTP‐C11‐N2F, BTP‐C9‐N2F, BTP‐C9‐IC4F, BTP‐C9‐N4F, designed synthesized by side‐chain shortening, end‐acceptor π ‐extension, fluorination. As a result, favorable...
Volcanic feature identification on topographic maps is an emerging area that can leverage advanced machine learning techniques. However, the field faces challenges due to scarcity of current labeled volcanic data, class imbalances, and limitations in existing models. Current approaches often fail effectively capture spatial continuity hierarchical patterns inherent terrains, particular for intraplate volcanism such as petit-spot volcanoes.This study began with manually data employed Support...
Abstract Removal and thinning of cratonic lithosphere is believed to have occurred under different tectonic settings, for example, near subduction zones above mantle plumes. Subduction‐induced modification has been widely discussed; however, the mechanisms dynamic processes plume‐induced lithospheric removal remain elusive require further systematic investigation. In this study, we use a series 2‐D thermo‐mechanical models explore dynamics due interaction between plume weak mid‐lithosphere...
Abstract Delamination of the lower lithosphere has occurred under different tectonic settings, thereby inducing strong lateral lithospheric strength heterogeneities. Here, we examine a recent case plume‐induced delamination associated with Yellowstone plume. We propose that interaction between plume and western North American is what led to beneath Columbia River Basalt (CRB) roughly ∼17 Myr ago. The excess melting when this “hole” was being filled by material primary trigger for CRB event....
Three nonfullerene acceptors with different aryl-substituted terminal groups were designed and synthesized. The optimal device obtained a PCE of 11.42%, nonradiative energy loss ≤0.16 eV. Non-rigid π-extension is proved to be feasible strategy modulate the molecular packing behaviour reduce recombination loss.
Delamination of the continental lithospheric mantle is well recorded beneath several continents. However, fate removed lithosphere has been rarely noted, unlike subducted slabs reasonably imaged in upper and mid mantle. Beneath former Gondwana, recent seismic tomographic models indicate presence at least 5 horizontal fast-wavespeed anomalies ~600 km depths that do not appear to be related slab subduction, including fast structures locations consistent with delamination associated Paraná...
Abstract Molecular stacking behavior exerts a significant influence on the blend film morphology of organic solar cells (OSCs), further affecting device performance and stability. Modulation molecular structure, such as central unit end‐group, can profoundly impact this process. Herein, four quinoxaline (Qx)‐fused‐core‐based non‐fullerene acceptors (NFAs), Qx‐N4F Qx‐ o/m/p ‐N4F are synthesized combining π‐extended end‐groups optimized units. The isomeric fluorinated units lead to changes in...

Abstract The Xianshuihe fault (XSHF) zone, characterized by intense tectonic activity, is located at the southwest boundary of Bayan Har block, where several major earthquakes have occurred, including 2008 Wenchuan and 2013 Lushan earthquakes. This study analysed underground temperature sequence data for four years seven measuring points different depths (maximum depth: 18.9 m) in southeastern section XSHF zone. High‐frequency atmospheric noise was removed from sequences to obtain relatively...
