High‐efficiency small‐molecule‐based organic photovoltaics (SM‐OPVs) using two electron donors ( p ‐DTS(FBTTh 2 ) and ZnP) with distinctively different absorption structural features are reported. Such a combination works well synergically improves device short‐circuit current density J sc to 17.99 mA cm −2 fill factor (FF) 77.19%, yielding milestone efficiency of 11%. To the best our knowledge, this is highest power conversion reported for SM‐OPVs date first time combine high over 17 FF 77%...
Photoactive materials comprising a siloxane-terminated side chain could enable active layers with high humidity tolerance and maintain efficiency.
Simple fused-ring nonfullerene acceptor BDDEH with benzobithiophenedione as core unit is obtained through organostannane-free and ligand-free direct heteroarylation approach for the first time, which delivers a high efficiency of 12.59% in PSCs.
The cost‐effectiveness of polymer solar cells is a very important concern for future applications. In this work, new combinatory side chain integrating siloxane terminal and alkoxy group developed, three polymers, PQSi05, PQSi10, PQSi25, with 5%, 10%, 25% contents the siloxane‐terminated chain, respectively, are successfully synthesized. As content increases, surface energy corresponding film decreases, showing tunable miscibility in blend films nonfullerene acceptor IT‐4F. A maximum power...
High hole mobility polymer and Y-series non-fullerene acceptor boost efficiency fill factor of thick-film solar cells.
Abstract Amorphous InGaZnO (a‐IGZO) thin‐film transistors (TFTs) would exhibit significant drain current drop (DCD) degradation at high voltage, which has been ascribed to the impact of hot carriers on lattice a‐IGZO films. This study unveils that interstitial oxygen (O i ) defects also contribute DCD degradation. It is inferred weak bonds near region be easily broken by carriers. Thus, acceptor‐like trap states are generated, leading aggravated deterioration DCD. In addition, it observed...
PBDB-T-SF : IDIC ID4F ternary blend films show 11.52% power conversion efficiency, higher than 9.39% and 10.35% for the corresponding binary devices.
This paper proposes a novel parameter matching method based on particle swarm optimization (PSO) algorithm for designing the parameters of LCC/S compensation topology dynamic wireless power transfer (DWPT) system under full resonance condition topology. Firstly, mathematical model topology, which is composed series inductors, parallel capacitors, and capacitors primary side, secondary side (LCC/S topology), derived established. After that, three factors, are affecting transmission...
Regioselective acylation was used to prepare aromatic substituted benzodithiophenediones (BDDs) and then construct new nonfullerene acceptors. Nonfullerene Ph-BDD with a bare benzene ring exhibited high efficiency of 13.64% good thermal storage stabilities.
With the fast development of magnetic coupling resonant-dynamic wireless power transfer (MCR-DWPT), it is more likely that high-efficiency charging between unmanned ground vehicles (UGVs) will be practically realized, especially in desolate places are far away from a city center or depot and always experiencing large load fluctuations, varying operating conditions, complex working targets. Based on this, UGVs demands higher reliability efficiency. This paper reviews MCR-DWPT system UGVs,...
An orthogonal solvent sequentially deposited active layer with complete interpenetration was achieved by casting an acceptor solution on polymer donor film, giving high efficiency in inverted organic solar cells.
Molecular orientation in polymer solar cells (PSCs) is a critical subject of investigation that promotes the quality bulk heterojunction morphology and power conversion efficiency (PCE). Herein, intrinsic transition can be found upon delicate control over branching point position irregular alkoxy side chain difluoroquinoxaline-thiophene-based conjugated polymers. Three polymers with points at third, fourth, fifth positions away from backbone were synthesized abbreviated as PHT3, PHT4, PHT5,...
Non-fullerene acceptors (NFAs) carrying a 1,1-dicyanomethylene-3-indanone (IC) end-group are the most powerful ones to boost power conversion efficiency of organic solar cells (OSCs). However, well-known Knoevenagel condensation mono-halogenated IC will result in an NFA isomeric effect, chemical issue that needs be addressed.

Most existing federated learning methods assume that clients have fully labeled data to train on, while in reality, it is hard for the get task-specific labels due users' privacy concerns, high labeling costs, or lack of expertise. This work considers server with a small dataset and intends use unlabeled multiple semi-supervised learning. We propose new framework generalized model, Federated Incremental Learning (FedIL), address problem how utilize separately scenario (FL). FedIL uses...
