Abstract Recently, benzene‐based solid additives (BSAs) have emerged as pivotal components in modulating the morphology of blend film organic solar cells (OSCs). However, since almost all substituents on BSAs are weak electron‐withdrawing groups and contain halogen atoms, study with non‐halogenated strong has received little attention. Herein, an additive strategy is proposed, involving incorporation benzene ring. An effective BSA, 4‐nitro‐benzonitrile (NBN), selected to boost efficiency devices. The results demonstrate that NBN‐treated device exhibits enhanced light absorption, superior charge transport performance, mitigated recombination, more optimal compared additive‐free OSC. Consequently, D18:BTP‐eC9+NBN‐based binary D18:L8‐BO:BTP‐eC9+NBN‐based ternary OSC processed by solvent achieved outstanding efficiencies 20.22% 20.49%, respectively. Furthermore, universality NBN also confirmed different active layer systems. In conclusion, this work demonstrates introduction electron‐absorbing moieties ring a promising approach design BSAs, which can tune achieve highly efficient devices, certain guiding significance for development BSAs.

Energy harvesting from cleaner sources and preserving the environment dangerous gasses are presently key priorities globally to maintain sustainable development. In this context, photovoltaic technology plays a vital role in generating energy ternary organic solar cells. Ternary cells display significant potential for achieving outstanding performance compared binary structures. Over past few years, endeavors develop novel materials have led consistent rise efficiency, surpassing 19% single-junction devices. our study, we simulated an inverted cell (TOSC) structure employing one-dimensional optical drift diffusion model using “Oghma-Nano 8.0.034” software by optimizing active blend thickness at 80 nm within of ITO/SnO2/PM6:D18:L8-BO/PEDOT:PSS/Ag. We different parameters such as EQE, Photo-CELIV, PCE, Jsc, Voc, FF with layer thicknesses ranging 50 200 discover behavior device terms efficiency parameters. Furthermore, attained PCE 20% Jsc 27.2 mA cm−2, Voc 0.89 V, 82.3%. This approach can potentially be valuable constructing highly effective TOSC laboratory.

Abstract Pursuing power conversion efficiency (PCE) is the priority of developing organic solar cells (OSCs) based on low‐cost completely non‐fused ring acceptors. Herein, a donor/acceptor re‐intermixing strategy to enhance photon capturing process, previously established well‐stratified active layer morphology reported. By adding 20 wt% PTQ10 (polymer donor) into acceptor's precursor, device PCE increased 16.03% from 15.11% D18/A4T‐16 control system, which attributed additional charge generation interface and suppressed bimolecular recombination. On contrary, using equal ratio PM6 leads significant loss, indicating importance considering vertical distribution perspective thermodynamics. Moreover, cutting‐edge level 17.21% for acceptor systems realized by altering PBQx‐TF/TBT‐26 PTQ11, via identical processing strategy. This work thus presents attractive engineering cell performance, as well in‐depth understanding.

Organic/silicon hybrid solar cells have attracted much interest due to their cheap fabrication process and simple device structure. A category of organic substances, Dibenzothiophene–Spirobifluorene–Dithiophene (DBBT-mTPA-DBT), comprises dibenzo [d,b] thiophene 3-(3-methoxyphenyl)-6-(4-methoxyphenyl)-9H-Carbazole, which function as electron donors. In contrast, methanone is an acceptor, with ∆Est 3.19 eV. This work focused on based the guest–host phenomena DBBT-mTPA-DBT CBP. Using a Si/poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) cell ultra-thin Dibenzothiophene–Spirobifluorene–Dithienothiophene (DBBT-mTPA-DBT) interlayer between Si Al led PCE 17.5 ± 2.5%. The substantially improved Si/Al interface, reducing contact resistance from 6.5 × 10⁻1 Ω·cm2 3.5 10⁻2 Ω·cm2. improvement increases transport efficiency silicon aluminum reduces carrier recombination. containing DBBT-mTPA-DBT/Al double-layer cathode shows 10.85% increase in power conversion relative standard device.
