Abstract Ternary organic solar cells (T‐OSCs) based on energy transfer can significantly boost the light absorption efficiency, thereby improving their power conversion efficiency (PCE). However, uncontrolled distribution of third component in bulk heterojunction (BHJ) device often results low ( E FRET ), and also tends to compromise interpenetrating network structure active layer. Herein, a localized deposition strategy is proposed establish with controlled (CDBHJ). Take PM6:Y6:IBC‐F for example, IBC‐F serves as donor PM6 acceptor. Compared BHJ‐based devices, proportion within phase increases from 25.1% 72.7%, enhancing 46.5% 66.8% CDBHJ‐based devices. Furthermore, improves crystallization separation kinetics during film‐forming process. Thus, exhibits superior exciton generation, diffusion, dissociation process, along higher more balanced charge transport. Consequently, achieves PCE 18.29%, which ranks among best PM6:Y6‐based T‐OSCs. This work demonstrates effectiveness controlling component, presenting an innovative pathway development highly efficient

Large-area and highly sensitive image sensors are vital for undercell fingerprint recognition technology. The photomultiplication-type organic photodetector (PM-OPD) is one of the alternative choices due to its special active layers with ratio donor acceptor by weight about 100:3 achieving single charge carrier transport channels, resulting in relatively low dark current density high external quantum efficiency under bias. optimal PM-OPDs exhibit a maximal 2.1 × 1012 Jones specific detectivity at 610 nm -6 V bias signal-to-noise 51,400 -5.2 Solution-processed were prepared onto top polycrystalline-silicon thin-film transistor readout circuit, successfully realized 338 pixels resolution per inch. electrical optical properties sensor investigated, high-quality images obtained.

Abstract At present, organic solar cells (OSCs) stand at a key stage of industrialization. Although many photovoltaic materials exhibit outstanding performance, they cannot meet the requirements for large‐scale production. Here, cost‐effective and high‐throughput method is reported to prepare Perylene/naphthalene‐diimide (PDI/NDI) non‐conjugated polymers serving as cathode interlayer (CIL) in OSCs. By utilizing low‐cost raw materials, NDI/PDI can be readily synthesized without involving purification by column chromatography, which minimizes cost CILs. Notably, performance PDI‐OEG CIL insensitive preparation conditions processing methods, thereby lowering technical threshold practical applications, essentially important using binary blend PM6:L8‐BO an active layer, OSC modified exhibited power conversion efficiency (PCE) 18.7%. It demonstrated that suitable work function, self‐doping effect, H‐aggregate endowed with excellent electron collection capability, suppress charge recombination Moreover, well‐compatible large‐area blade‐coating technique, 1‐cm 2 fabricated blade‐coated PDI‐OEG, delivering PCE 17.0%. The results suggest promising material advancing industrialization technology.
