Organic light-emitting diodes (OLEDs) have been successfully developed and now entered the commercial marketplace. Besides impressive performance as displays, one of key advantages OLEDs is that they can potentially be made entirely by solution process thus are more suitable for low cost, large area flexible displays white lighting panels. To realize this, many efforts devoted on development processable materials charge transporting well electrode materials, which resulted in successful...
The majority of organic semiconductors have a low relative dielectric constant (εr < 6), which is an important limitation for solar cells (OSCs). A high would reduce the exciton binding energy, charge carrier recombination losses, and thereby enhance overall device performance OSCs. However, development organic/polymeric with higher constants > 6) has attracted very limited attention. Moreover, OSCs based on photovoltaic materials are still in their infancy. Herein, we report oligoethylene...
The effects of Au nanoparticles (NPs) incorporated into the active layer polymer solar cells (PSCs) with a newly synthesized donor are investigated in detail. Our work shows that localized surface plasmon resonance (LSPR) introduced by metallic NPs can experimentally and theoretically enhance light absorption PSCs because strong LSPR near field mainly distributes laterally along layer. understanding be applied to other NP organic cells. Meanwhile, our results show electrical properties...
All-polymer solar cells (all-PSCs) composed of conjugated polymers as both donor and acceptor components in bulk heterojunction photoactive layers have attracted increasing attention.

Abstract Benefiting from low cost and simple synthesis, polythiophene (PT) derivatives are one of the most popular donor materials for organic solar cells (OSCs). However, polythiophene‐based OSCs still suffer inferior power conversion efficiency (PCE) than those based on donor–acceptor (D–A)‐type conjugated polymers. Herein, a fluorinated derivative, namely P4T2F‐HD, is introduced to modulate miscibility morphology bulk heterojunction (BHJ)‐active layer, leading significant improvement OSC...
Abstract The power conversion efficiencies (PCEs) of organic solar cells (OSCs) have increased rapidly owing to the development non‐fullerene acceptors (NFAs). However, polymer donors lags behind significantly. Currently, are dominated by a handful thiophene‐substituted benzo[1,2‐b:4,5‐b']dithiophene (BDTT) polymers, which suffer from lengthy synthesis and high production cost. Compared with BDTT‐based oligothiophene‐based donor‐acceptor polymers feature much easier synthesis, were...
Suppressing the photon energy loss (Eloss ), especially non-radiative loss, is of importance to further improve device performance organic solar cells (OSCs). However, typical π-conjugated semiconductors possess a large singlet-triplet gap (ΔEST leading lower triplet state than charge transfer and contributing channel photocurrent by state. Herein, series polymer donors are developed introducing BNIDT block into PM6 backbone. The high electron affinity opposite resonance effect BN bond in...
Abstract Detecting short‐wavelength infrared (SWIR) light has underpinned several emerging technologies. However, the development of highly sensitive organic photodetectors (OPDs) operating in SWIR region is hindered by their poor external quantum efficiencies (EQEs) and high dark currents. Herein, high‐sensitivity SWIR‐OPDs with an efficient photoelectric response extending up to 1.3 µm reported. These OPDs utilize a new ultralow‐bandgap molecular semiconductor featuring quinoidal tricyclic...
Abstract Nonfused ring electron acceptors (NFREAs) are promising candidates for future commercialization of organic solar cells (OSCs) due to their simple synthesis. Still, the power conversion efficiencies (PCEs) NFREA‐based OSCs have large room improvement. In this work, by merging end group halogenation and side chain engineering, we developed four A–D–A'–D–A type NFREAs, which refer as EH‐4F, C4‐4F, EH‐4Cl, C4‐4Cl. Single crystal X‐ray diffraction revealed that multiple intermolecular...
