Abstract Inorganic metal oxides and salts are widely employed as hole‐transporting layers (HTLs) in organic solar cells (OSCs) due to their advantages of low cost facile preparation. However, issues such severe agglomeration can negatively impact film quality, leading reduced reproducibility device stability. To address these challenges, this work reports the synthesis a vanadium trichloride‐benzene tricarboxylic acid (BTC) complex (denoted VB) via sol‐gel process under mild conditions (60 °C annealing). The VB demonstrates well‐aligned energy levels enhanced conductivity when integrated with PM6:L8‐BO active layer. Consequently, binary OSCs incorporating HTL achieve high‐power conversion efficiency (PCE) up 19.60%. Notably, processing technique offers versatile approach for fabrication metal‐organic complex, resulting uniform dense film. robust coordination network structure endows VB‐based exceptional thermal stability, evidenced by T 80 (PCE retention 80% initial value) lifetime 5142 h, which is among best performances reported state‐of‐the‐art OSCs.

The appearance of the cathode interlayer (CIL), a transition bridge between and organic photoactive layer (OPL), provides new pathway for performance improvement solar cells (OSCs). PFN-Br is widely employed in many optoelectronic devices, including nonfullerene OSCs, to transport electrons improve charge injection at interface. However, due relatively low conductivity PFN-Br, thickness CIL prepared with usually less than 10 nm, which evidently contradicts requirements large-scale roll-to-roll manufacturing. Herein, strategy using N-α-carbobenzyloxy-d-Arginine (NA) as doping material proposed PFN-Br. homogeneous distribution NA can modify work function (WF) facilitate an interface dipole arrangement that favorable transfer, resulting binary CILs tunable WF increased conductivity. To verify this method, series devices were PBDB-T:IT-M or PM6:Y6 OPL different proportions CIL. use PFN-Br:NA (0.75:0.06, weight%) helps morphology, making it exhibit trend fiber network structure, leading higher fill factor short circuit current density. Consequently, optimal power conversion efficiency (PCE) based on from 10.5% 11.1% 15.4% 16.0%, respectively. In addition, NA-doped device exhibits better nitrogen stability after 360 h dark storage compared control. discovery these modification approaches insight into hybrid interlayers required efficient reliable OSCs.

This approach successfully enables delicate tuning development high‐performance OSCs (PCE = 18.5%). enhances compatibility SMAs with hydrophobic D18 polymer donor, promoting formation intermixed donor/acceptor domains efficient charge generation. Meanwhile, improves SMA aggregation crystallinity, facilitating strong interconnected assembly transport. As result, binary based on D18:SMA‐Ph‐CF achieve significantly higher PCE 18.5%, compared 14.3% D18:SMA‐CH 16.5% D18:SMA‐CF OSCs. These results highlight importance optimizing
