Abstract Fullerene acceptors typically possess excellent electron-transporting properties and can work as guest components in ternary organic solar cells to enhance the charge extraction efficiencies. However, conventional fullerene small molecules suffer from undesirable segregation dimerization, thus limiting their applications cells. Herein we report use of a poly(fullerene- alt -xylene) acceptor (PFBO-C12) component enables significant efficiency increase 16.9% for binary 18.0%...
Abstract The elaborate balance between the open‐circuit voltage ( V OC ) and short‐circuit current density J SC is critical to ensure efficient organic solar cells (OSCs). Herein, chalcogen containing branched chain engineering employed address this dilemma. Three novel nonfullerene acceptors (NFAs), named BTP‐2O , BTP‐O‐S BTP‐2S featuring different peripheral chains are synthesized. Compared with symmetric grafting two alkoxy or alkylthio chains, asymmetric one shows mediate absorption...
Organic semiconductors (e.g., PCBM and IDIC) frequently serve as interface passivants for perovskite solar cells (PSCs) due to their beneficial passivation effects on interfaces. However, the interiors of films is greatly limited by poor solubility in polar solvents compatibility issues. Here facile synthesis organic semiconductor nanoparticle (NP) that readily disperse inks reported. Adding these NPs into not only modulates crystallization, improves film quality conductivity, but also...
Electron transporting materials (ETMs) play vital roles in determining the efficiency and stability of inverted perovskite solar cells. The widely used PCBM is prone to undesirable aggregation migration a cell, thus impairing device stability. In this work, we develop new type ETMs by polymerizing C60 fullerene with an aromantic linker unit. resultant polyfullerene (PFBS-C12) not only maintains good optoelectronic properties fullerenes, but also can address aforementioned problem PCBM....
Current high-efficiency organic solar cells (OSCs) are generally fabricated in an inert atmosphere that limits their real-world scalable manufacturing, while the efficiencies of air-processed OSCs lag far behind. The impacts ambient factors on cell fabrication remain unclear. In this work, effects systematically investigated, and it is unveiled oxidation doping light absorbers dominant reasons causing degradation when air. To address issue, a new strategy for fabricating high-performance by...
Organic thin-film transistors (OTFTs) with ideal behavior are highly desired, because nonideal devices may overestimate the intrinsic property and yield inferior performance in applications. In reality, most polymer OTFTs reported literature do not exhibit characteristics. Supported by a structure-property relationship study of several low-disorder conjugated polymers, here, we present an empirical selection rule for candidates textbook-like high reliability factors (100% transistors). The...
A group of regioregular polymer acceptors is synthesized by polymerizing Y6 moieties with different linker units including thiophene, vinylene, 2,2'-bithiophene, and thieno[3,2-b]thiophene, their optoelectrical properties photovoltaic performances are studied systematically. It found that the have significant impacts on backbone planarity, conjugation, hence acceptors. The vinylene-based PYF-V-o shows a smaller dihedral angle between end groups vinylene more rigid backbone, thus affording...
The communication between mitochondria and the endoplasmic reticulum (ER) is facilitated by a dynamic membrane structure formed protein complexes known as mitochondria-associated membranes (MAMs). structural functional integrity of MAMs crucial for insulin signal transduction, relying heavily on their regulation intracellular calcium homeostasis, lipid mitochondrial quality control, stress (ERS). This article reviews recent research findings, suggesting that exercise may promote remodeling...
Ultraviolet (UV) radiation poses a substantial challenge to the stability of prevalent p-i-n (positive-intrinsic-negative) perovskite solar cells (PSCs), demanding more robust hole-transport layers (HTLs) due light incident from HTL side. Here, we unveil that commonly used self-assembled monolayer (SAM)–type HTLs suffer poor UV causes irreversible damage hole extraction and impairs device stability. To address this issue, develop polymeric UV-stable named Poly-2PACz, which exhibits strong...
Abstract N doping is an essential strategy to prolong electron diffusion length and improve the photovoltaic performance of p–i–n structured perovskite solar devices, but current n‐dopants generally suffer from air instability, poor compatibility with perovskites, compensation intrinsic defects, thus limiting their effectiveness. To address these issues, in this work, a new n‐doping developed by incorporating air‐stable n‐dopant (1‐ethyl‐3‐methylimidazolium‐2‐carboxylate, EMIC) that has no...

Despite the progress made in non-fullerene acceptor (NFA) based organic solar cells (OSCs), it is quite challenging to achieve efficient green solvent processed (GSP) OSCs. Herein, we synthesize three asymmetric NFAs (BTP-SO-BrF, BTP-SO-1F, and BTP-SO-2F) with alkoxy/alkythio chains on core unit but distinct ending groups (BrF-IC, 1F-IC, 2F-IC), respectively. The alkoxy/alkylthio help enhance solubility of compatibility PM6 polymer donor non-halogen solvents. Furthermore, group modulation...
