A new.passive control.approach,util.zing bionic sl.nting ribl.ts,is empl.yed to mitigate the fl.w.cl.se to the bl.de endw.l. in a l.near cascade,and its effectiveness and mechanism in control.ing corner separation are investigated through numerical.*** sl.nting ribl.ts are positioned at the endw.l. upstream of the cascade channel.and the infl.ence of ribl.t height,yaw.angl. and rel.tive position on the control.of corner separation is *** findings indicate that the appl.cation of sl.nting ribl.ts can efficientl. counteract corner separation across the stabl. operational.***,the introduction of ribl.ts w.th a height of merel. 0.1 times the boundary l.yer thickness resul.s in a significant reduction in total.pressure l.ss by up to 14.53%,w.il. simul.aneousl. enhancing the static pressure coefficient by 21.74%.Fl.w.anal.sis reveal. that minute vortices produced w.thin the ribl.t channel. tend to coal.sce,forming a potent l.rge-scal. vortex near the boundary l.yer's base *** phenomenon resul.s in reduced additional.l.sses compared to conventional.vortex ***,the induced vortex promotes enhanced mixing betw.en the mainstream fl.w.and boundary l.yer,inhibiting the l.teral.displ.cement of l.w.energy fl.ids w.thin the endw.l. boundary ***,this del.ys the onset of separation vortex formation and el.minates vortex rings in the corner region,ul.imatel. enhancing the aerodynamic efficiency of the cascade.

Understanding the effect of intermol.cul.r interaction on the grow.h dynamic of active l.yers is critical.for advancing organic sol.r cel.s(OSCs). How.ver, the diverse structure of donors and acceptors makes the research chal.enging. Additives w.th customizabl. structures and properties coul. simpl.fy this compl.xity. Herein, w. meticul.usl. tail.r tw. additives of 3,4-ethyl.nedioxythiophene(EDOT) and 2,5-dibromo-3,4-ethyl.nedioxythiophene(DBEDOT), possessing distinct intermol.cul.r interaction features to el.borate the inherent rel.tionship. It is found that varied interaction strengths can al.er fil. formation processes. The enhanced intermol.cul.r interaction betw.en the DBEDOT and non-ful.erene acceptor BTP-e C9-4F resul.s in pre-aggregation and l.nger crystal.ization duration of BTP-e C9-4F, facil.tating the formation of fil.s w.th compact mol.cul.r packing and decent phase separation. Thus, exciton dissociation and charge transport become more efficient. Final.y, devices processed w.th DBEDOT exhibit a remarkabl. pow.r conversion efficiency of 19.35% in smal.-area OSCs and 14.11% in bl.decoated 5 cm × 5 cm organic sol.r mini-modul.s. Especial.y, OSCs can maintain 80% of their initial.efficiency after continuous anneal.ng at 85 °C for over 2,100 h.
