The determination of molecular conformations oligomeric acceptors (OAs) and their impact on packing are crucial for understanding the photovoltaic performance resulting polymer solar cells (PSCs) but have not been well studied yet. Herein, we synthesized two dimeric acceptor materials, DIBP3F-Se DIBP3F-S, which bridged segments Y6-derivatives by selenophene thiophene, respectively. Theoretical simulation experimental 1D 2D NMR spectroscopic studies prove that both dimers exhibit O-shaped...
Abstract The commercial viability of all‐small‐molecule (ASM) organic solar cells (OSCs) requires high efficiency, long‐term stability, and low‐cost production. However, satisfying all these factors at the same time remains highly challenging. Herein, a volatile solid additive, namely, 1,8‐dichloronaphthalene (DCN) is demonstrated to simultaneously enhance power conversion efficiency (PCE) storage, thermal as well photo stabilities oligothiophene ASM‐OSCs with concise syntheses. improved...
Non-fullerene based organic solar cells display a high initial power conversion efficiency but continue to suffer from poor thermal stability, especially in case of devices with thick active layers. Mixing five structurally similar acceptors electron affinities, and blending donor polymer is explored, yielding up 17.6%. The hexanary device performance unaffected by annealing the bulk-heterojunction layer for at least 23 days 130 °C dark an inert atmosphere. Moreover, blends offer degree...
Our findings unveil the structure-property relations and elucidate key rules for highly efficient outdoor-stable terpolymer photovoltaics, paving path to commercialization.
Feline infectious peritonitis (FIP), caused by virulent feline coronavirus, is the leading cause of death in cats. The type I interferon (type IFN)-mediated immune responses provide host protection from diseases. Several coronaviruses have been reported to evolve diverse strategies evade IFN response. However, whether virus (FIPV) antagonizes signaling remains unclear. In this study, we demonstrated that FIPV strain DF2 infection not only failed induce interferon-β (IFN-β) and...
Abstract Long exciton diffusion length ( L D ) is key to maximizing excitation harvesting in organic solar cells, but contradicting values are reported for non‐fullerene acceptors (NFA). To understand the factors enabling large , experimental observation of decay by transient absorption spectroscopy (TAS) combined with microscopic Kinetic Monte Carlo (KMC) simulations on 4 ITIC derivatives. Exciton decays fitted considering singlet exciton‐singlet annihilation (SSA) and intrinsic exciton's...
Non-fullerene acceptor (NFA)-based ternary bulk heterojunction solar cells (TSC) are the most efficient organic (OSCs) today due to their broader absorption and quantum efficiencies (QE) often surpassing those of corresponding binary blends. We study how energetics driving charge transfer at electron donor:electron (D/A) interfaces impact QE in blends PBDB-T-2F donor with several pairs lower bandgap NFAs. As blends, ionization energy offset between ({\Delta}IE) controls maximizes for...
Durable and high-performing anion exchange membranes (AEMs) are central components in alkaline water electrolyzers fuel cells. Here, we have pursued a synthetic strategy where heteroatom-free polymer backbones functionalized with alkali-stable dimethyl piperidinium (DMP) cations via flexible spacers. We achieved this design by synthesizing trifluorobenzophenone monomer carrying piperidine group the 4-position straightforward Friedel–Crafts acylation of 4-(3-phenylpropyl)piperidine....
Inspired by the embedding representation in Natural Language Processing (NLP), we develop a financial embedded vector model to abstract temporal characteristics of time series. Original features are discretized firstly, and then each set is considered as “word” NLP, while whole series corresponds “sentence” or “paragraph”. Therefore models NLP could be applied To test proposed model, use RBF neural networks regression predict comparing vectors input with original features. Numerical results...
Perovskite light-emitting diodes (LEDs) have emerged as a potential solution-processible technology that can offer efficient light emission with high color purity. Here, we explore the device physics of perovskite LEDs using simple analytical and drift-diffusion modeling, aiming to understand how distribution electric field, carrier densities, recombination in these devices differs from those assumed other technologies such organic LEDs. High barriers electron hole extraction are responsible...
DC distributed power systems (DPSs) have attained much attention because of its characteristics high efficiency, density and flexible configuration. However, when converters are interconnected in a system, adverse interactions may occur due to the converter sensitivity external impedance, these degrade transient performance or cause stability issues. Currently, research mainly focuses on DPS with voltage bus, including analysis approaches improve system stability. This study is establish...
Anion exchange membranes (AEMs) are critical components of alkaline membrane water electrolyzers and fuel cells that under development today [1,2]. Consequently, there is a strong demand for highly conductive alkali-stable AEMs. In this context, polyhydroxyalkylation has emerged as one the most efficient synthetic pathways to chemically resistant polymer backbones these Friedel-Crafts type polycondensations, an electron-rich aromatic compound reacts with activated ketone or aldehyde produce...
