Опубликована: Фев. 5, 2025

The morphology of active layer the organic solar cells (OSCs) tends to transition toward its lowest energy conformation under thermal stress, significantly limiting stability OSCs. In this study, ethyl cellulose (EC) is utilized as an additive in typical PM6:Y6 and other systems. Due strong interaction between hydroxyl groups EC heteroatoms semiconductors, their bulk heterojunction nanomorphology locked, thereby enhancing device stability. Under stress at 65 °C for 1,000 h, incorporating demonstrates excellent nearly without performance loss. Furthermore, compared control device, exhibits improved a range more stringent aging conditions. Additionally, shows broad applicability various systems, effectively This work offers promising approach developing stable structures

Conjugated microporous polymers (CMPs), featuring photoactive structures, a high surface area, robust thermal stability, and facile modulation, provide versatile platform for fabricating diverse heterogeneous photocatalysts. The incorporation of donor–acceptor (D–A) structures into CMPs to increase their charge separation potential enhance the photocatalytic efficacy is viable strategy. In this work, we designed synthesized unique set D–A monomers, incorporating boranil dyes as electron-deficient moieties carbazoles electron-rich subunits. Subsequently, were prepared via an economical environmentally friendly oxidation coupling reaction, in reactions was investigated. Modulation polymer's photoelectronic properties performance can be achieved by adjusting content monomer. polymer pCZFB-3, with highest units, exhibited optimal activity. This finding confirms that strengthening effect significantly catalyst's catalytic efficacy. study presents insights designing innovative photocatalysts based on boron-containing dyes.

Abstract This quantum mechanical approach recommends push–pull molecular engineering to fabricate hole‐transporting materials (HTMs) for photovoltaic cells. It integrates acceptor moieties via thiophene fluorene core, resulting in five novel HTMs (SFD‐1 SFD‐5). The results exhibit that derivative show excellent coherence excitation, dispersion, and transportation of charge carriers, ensuring robust hole mobility. anchor functionalized unveil band alignment with perovskite fitting HOMO energy levels (−4.93–−5.35 eV), less optical absorption visible portion ( < 520). integration has improved the mobility derivatives, accredited smaller reorganization (0.14–0.68 greater transfer integral (0.22–0.33 eV). transition density matrix analysis exhibited electronic coupling, subtler carrier overlapping length (7.48–13.73 Å). resulted an upsurge intrinsic transference (70.75–92.70%) exciton binding energy, leading easier dissociation, fewer recombination fatalities. However, adequate variation dipole moment (4.04 D 16.34 D) Gibbs solvation‐free (−18.06 −21.89 kcal mol −1 ) ensures facile film formation processability. In conclusion, this these flourene‐based are highly desireable forthcoming solar cell technology.
