For photovoltaic polymers with a D-π-A backbone, there are great deal of D and A units, but the choice π bridge is relatively limited thiophene (T) still most effective one. Here, we utilize two polymers, J52-FS as PE2 thieno[3,2-b]thiophene (TT) bridge, to combine low band-gap non-fullenere Y6, respectively. The cells based on PE2:Y6 can realize PCE 13.50%, which obviously higher than 10.58% J52-FS:Y6 analogue. Our work demonstrates that using TT π-bridge simple promising approach construct...
Perovskite solar cells (PSCs) have emerged as prominent contenders in photovoltaic technologies, reaching a certified efficiency of 26.7%. Nevertheless, the current record is still far below theoretical Shockley-Queisser...
Abstract In the last decade, laboratory-scale single-junction perovskite solar cells have achieved a remarkable power conversion efficiency exceeding 26.1%. However, transition to industrial-scale production has unveiled significant gap. The central challenge lies in difficulty of achieving uniform, high-quality films on large scale. To tackle this issue, various innovative strategies for manipulating crystallization emerged recent years. Based an in-depth fundamental understanding...
Abstract Poly(3‐hexylthiophene) (P3HT) acting as one of the most popular and low‐cost polymers is quite suitable for commercialization organic solar cells but suffers from low power conversion efficiency (PCE) because limited matching non‐fullerene acceptors (NFAs). One important reason that restricts enhancement remains unresolved undisclosed contributions subtle structure modification to obvious performance change. In combination with previous reports this work, herein A 2 ‐A 1 ‐D‐A type...

Then, influence factors, including containment, detection, success efficiency, sorted out, objective function optimization Subsequently,...
As global manufacturing competition increasingly emphasizes supply chain resilience, enhancing the risk resistance of chains through digital empowerment has become a critical priority. This study leverages opportunities economy to deeply investigate mechanisms that enhance resilience. Using data from China’ s A-share listed companies 2012 2020, research framework is constructed based on information asymmetry and transaction cost theories. Employing text analysis factor analysis, develops...
Physical-layer key generation (PKG) based on channel reciprocity has recently emerged as a new technique to establish secret keys between devices. Most works focus pairwise communication scenarios with single or small-scale antennas. However, the fifth (5G) wireless communications employ massive multiple-input multiple-output (MIMO) support multiple users simultaneously, bringing serious overhead of reciprocal acquisition. This paper presents multi-user in MIMO networks. We provide beam...
We review the development of TT-bridged D–π–A copolymers and emphasize role played by TT-bridge on tuning polymer properties improving device performance.
An air-stable 2-(anthracen-9-yl)-1<italic>H</italic>-inden-3-yl dicyclohexylphosphine was used in palladium-catalyzed borylation/Suzuki–Miyaura cross-coupling reaction.
Three 6-fluoro-thieno[2′,3′:4,5]benzo[1,2-d][1,2,3]triazole (fBTAZT) containing copolymers, named as PfBTAZT-H, PfBTAZT-F, and PfBTAZT-Cl, were employed to pair with a benzo[1,2-d][1,2,3]triazole (BTA) based non-fullerene acceptor BTA3 for the applicaition in organic solar cells (OSCs). By introducing fluorine or chlorine atoms into thiophene side chains on BDT units, highest occupied molecular orbital (HOMO) energy levels of polymers shift down sequence, PfBTAZT-Cl shows an obvious...
On the basis of success "Same-Acceptor-Strategy" (SAS) in constructing p-type and n-type photovoltaic material combination to realize high open-circuit voltage (VOC) beyond 1.1 V, we designed synthesized two new benzotriazole (BTA)-based conjugated polymers. PE1 was derived from classical polymer J61 by replacing thiophene π-bridge with thieno[3,2-b]thiophene (TT) due its rigid structure linear backbone conformation, which are benificial for enhancing effective conjugation length...
To study the impact of introducing fluorine atoms onto conjugated phenyl side chains benzo[1,2-b:4,5-b′]dithiophene (BDT)-based copolymers, three novel donor−π–acceptor (D−π–A) alternative polymers PE40, PE42, and PE44 were designed synthesized. The phenyl-substituted-BDT, thieno[3,2-b]thiophene, benzo[d][1,2,3]triazole (BTA) served as donor, π-bridge, acceptor units, respectively, to enable linear polymer backbones. When two or four into units PE42 demonstrate a gradual decrease energy...

In the context of global energy transition and climate change, system resilience has become critical for countries worldwide. While green digital infrastructure—emerging from integration digitalization low-carbon development—shows theoretical potential to strengthen resilience, empirical evidence remains limited. This study utilizes China’s 2015 Green Data Center Pilot Policy as a quasi-natural experiment examine this relationship through comprehensive panel data 30 Chinese provinces...
<title>Abstract</title> Perovskite and organic semiconductors exhibit analogous properties, including bandgap tunability, low-temperature solution processing, high potential for lightweight applications. These similarities render them highly attractive being integrated in multijunction architecture: perovskite-organic tandem solar cells (POTSCs). Nevertheless, the efficiency of POTSCs is limited by electrical losses, which stem from both wide-bandgap (WBG) perovskite layers interconnecting...

Conjugated polymers with D-π-A backbone structures have been intensively investigated and largely promoted the rapid progress of organic solar cells (OSCs). However, as one simplest electron-accepting (A) units, phthalimide (PhI) only attracts less attention to construct promising photovoltaic in OSC community. Thus, correlations among chemical structure, optoelectronic properties, performance need be systematically investigated. Here, we combined PhI moiety electron-donating (D) unit...
