In this work, we have introduced single/double-sided N-annulated perylene bisimide (PBI) with deep energy levels into double-cable polymers poly[1-(5-(4,8-bis(4-chloro-5-(2-ethylhexyl)thiophen-2-yl)-6-methylbenzo[1,2-b:4,5-b']dithiophen-2-yl)thiophen-2-yl)-5,7-bis(2-ethylhexyl)-3-(5-methylthiophen-2-yl)-4H,8H-benzo[1,2-c:4,5-c']dithiophene-4,8-dione] (PBDB-T-Cl) as a donor backbone, marking s-PPNR and as-PPNR, according to the molecular symmetry. Both displayed high open-circuit voltage approaching 1.20 V in light of level discrepancy between electron-donating electron-withdrawing parts, which is highest among double-cable-based single-component organic solar cell (SCOSC) devices. Additionally, asymmetric polymer improved absorption spectra, thereby promoting crystallization phase separation. Consequently, as-PPNR-based SCOSCs achieved power conversion efficiency 5.05% along higher short-circuit current density fill factor than their s-PPNR-based counterparts. successfully incorporated PBI revealed important effects on structural symmetry separation for SCOSC performance.

Abstract Ambient energy harvesting has great potential to contribute sustainable development and address growing environmental challenges. Converting waste from energy-intensive processes systems (e.g. combustion engines furnaces) is crucial reducing their impact achieving net-zero emissions. Compact harvesters will also be key powering the exponentially smart devices ecosystem that part of Internet Things, thus enabling futuristic applications can improve our quality life homes, cities, manufacturing, healthcare). To achieve these goals, innovative materials are needed efficiently convert ambient into electricity through various physical mechanisms, such as photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, radiofrequency wireless power transfer. By bringing together perspectives experts in types materials, this Roadmap provides extensive insights recent advances present challenges field.

The poor operational stability of non-fullerene electron acceptor (NFA) organic solar cells (OSCs) currently limits their commercial application. While previous studies have primarily focused on the degradation NFA component, we also consider here donor material. We examine three representative polymers, PM6, D18, and PTQ10, paired with benchmark NFA, Y6. After light soaking PM6 D18 in air, find an enhanced conversion singlet excitons into trapped interchain polaron pairs sub-100 femtosecond timescales. This process outcompetes transfer to Y6, significantly reducing charge generation yield. However, this pathway is absent PTQ10. identify twisting benzo[1,2-b:4,5-b′]dithiophene (BDT)-thiophene motif shared by as cause. By contrast, PTQ10 does not contain structural has improved stability. Thus, show that polymer can be a weak link for OSC stability, which must addressed collectively NFA.

This work covers the development of non-fullerene acceptors for use in organic photovoltaics built using N-annulated perylene diimide dye. The classic dye has been extensively used to construct acceptors, leading device power conversion efficiencies over 10%. Strong visible light absorption and deep frontier molecular energy levels have made such materials (both polymeric) near ideal pairing with narrow-gap conjugated polymers bulk-heterojunction active layers. N-annulation provides an extra site side-chain engineering alters electronic structure polycyclic aromatic core. In addition, allows selective bromination core, building blocks that are useful construction large frameworks atom-economical direct heteroarylation cross-coupling method.
