Breakthroughs of fullerene in optoelectronic devices—An overview

Hybrid Advances, Год журнала: 2024, Номер 6, С. 100233 - 100233

Опубликована: Июнь 26, 2024

This state-of-the art review is designed to state the competence of fullerene nanostructures in optoelectronic devices. Fullerene molecules own valuable structural, electronic, optical, electrical, and physical properties be employed optoelectronics device sector. Especially, modification nanocomposite formation led high performance light emitting diodes, optical sensors, photovoltaics systems. Combination conjugated polymers/molecules with has found further enhance efficacy towards these In form, have been known develop conjugation conducting polymers for better charge, hole, or electron transference leading assistances. Consequently, like poly(3-hexylthiophene), poly(3,4-ethylenedioxythiophene), poly(3-hexylthiophene-2,5-diyl), polystyrene sulfonate, polycyclopenta-dithiophene-benzothiadiazole, poly(2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene), 4,4′-bis[(p-trichlorosilylpropylphenyl)phenylamino] biphenyl, etc. reinforced utilized. Polymers grafted fullerenes such as [6,6]-phenyl C61-butyric acid methyl ester [6,6]-phenyl-C61-butyric hexyl also recognized. addition, non-conducting poly(methyl methacrylate) was exploited. Mostly, C60 C70 preferred nanofiller assemblies. Effectiveness nanomaterials observed luminescent solar cells (bulk heterojunction/polymer/perovskite), sensors (photo-/organic/bacterial sensing). Nevertheless, designs need comprehensively investigated by overcoming underlying working mechanism, fabrication, challenges related fields.

End‐extended Conjugation Strategy to Reduce the Efficiency‐Stability‐Mechanical Robustness Gap in Binary All‐Polymer Solar Cells

Angewandte Chemie International Edition, Год журнала: 2024, Номер unknown

Опубликована: Окт. 10, 2024

Concurrently achieving high efficiency, mechanical robustness and thermal stability is critical for the commercialization of all-polymer solar cells (APSCs). However, APSCs usually demonstrate complicated morphology, primarily attributed to polymer chain entanglement which has a detrimental effect on their fill factors (FF) morphology stability. To address these concerns, an end-group extended acceptor, PY-NFT, was synthesized studied. The analysis showed tightly ordered molecular packing mode favorable phase separation formed. PM6 : PY-NFT-based device achieved exceptional PCE 19.12 % (certified as 18.45 %), outperforming control PY-FT devices (17.14 %). This significant improvement highlights record-high binary APSCs. aging study revealed that PY-NFT blend exhibited excellent morphological stability, thereby superior retaining 90 initial efficiency after enduring stress (65 °C) 1500 hours. More importantly, film outstanding ductility with crack onset strain 24.1 %. Overall, rational chemical structure innovation, especially conjugation extension strategy trigger appropriate stable key improved robust
