Organic photovoltaics (OPVs) suffer from a trade-off between efficient charge transport and suppressed nonradiative recombination due to the aggregation-induced luminance quenching of organic semiconductors. To resolve this grand challenge, π-extended nonfullerene acceptor (NFA) B6Cl with large voids among honeycomb network is designed introduced into photovoltaic systems. We find that presence small amount (i.e., 0.5 or 1 wt %) can compress molecular packing host L8-BO, leading shortened...
UV-light illumination converts the aromatic conformation of polymer donors into a rigid quinone structure, resulting in compact fibrillar aggregation active layer to achieve maximum efficiency 19.9% single-junction organic solar cells.
Constructing fibril morphology has been believed to be an effective method of achieving efficient exciton dissociation and charge transport in organic solar cells (OSCs). Despite emerging endeavors on the fibrillization semiconductors via chemical structural design or physical manipulation, tuning geometry, i.e., width length, for tailored optoelectronic properties remains studied depth.

Abstract Realizing fibrillar molecular framework is highly encouraged in organic solar cells (OSCs) due to the merit of efficient charge carrier transport. This however mainly achieved via chemical structural design photovoltaic semiconductors. In this work, through utilization three alkoxythiophene additives, T‐2OMe, T‐OEH, and T‐2OEH, intermolecular interactions among a series BDT‐type polymer donors, i.e., PM6, D18, PBDB‐T, PTB7‐Th, are tuned self‐assemble into nanofibrils during solution...
Abstract Insulating polymers are promising components for constructing high performance organic solar cells (OSCs) due to their advantages including low cost, excellent mechanical properties, and feasibility in morphology modulation. However, few studies have been conducted on the effect of molecular weight insulating corresponding OSCs. In this work, polymethyl methacrylate (PMMA) with different (named as PMMA L H ) incorporated into a range polymer:nonfullerene photovoltaic systems. It is...
Polymeric semiconducting materials struggle to achieve fast charge mobility due low structural order. In this work, five 1H-indene-1,3(2H)dione-benzene structured halogenated solid additives namely INB-5F, INB-3F, INB-1F, INB-1Cl, and INB-1Br with gradually varied electrostatic potential are designed utilized regulate the order of polymer donor PM6. Molecular dynamics simulations demonstrate that although dione unit these tends adsorb on backbone PM6, reduced halogen-substituted benzene can...
Grid-forming (GFM) converters play a vital role in future power systems due to their ability independently establish voltage and frequency. However, interaction with AC circuits may give rise synchronous oscillations, which pose threat system stability dynamic performance. This paper investigates the issue of oscillations proposes an ultra-local model predictive control strategy for suppression. First, small-signal is developed analyze mechanism behind these oscillations. It revealed that...

Deadlocks are critical problems afflicting parallel applications, causing software to hang with no further progress. Existing detection tools suffer not only from significant recording performance overhead, but also excessive memory and/or storage overhead. In addition, they may generate numerous false alarms. Subsequently, after have been reported, tremendous manual effort is required confirm and fix these deadlocks. This paper designs a novel system, UnDead, that helps defeat deadlocks in...
