["Obtaining a well-accurate vertical distribution active layer morphology through the air-printing process is an essential task for achieving efficient scalable large-area organic solar cells (OSCs). In this target, the desired and controllable pseudo planar heterojunction (PPHJ) active layer structure with suitable phase separation is developed by pre-deposited D18-Cl layer under the PM6:BTP-eC9 film via an eco-friendly manufacturing method. The addition of the D18-Cl regulates molecular crystallization and leads to an ideal vertical stratification while simultaneously suppressing voltage loss, optimizing energetic disorder, and carrier management. Impressively, the optimal PPHJ devices perform superior power conversion efficiencies (PCEs) of 19.05% (100 nm), 17.33% (300 nm), and 14.14% (4 cm2) compared to the BHJ devices. Importantly, the PPHJ OSCs also exhibit an impressive extrapolated T80 (the time required to reach 80% of initial PCE) of long-time storage and operational stability, as well as thermal stability.","A pseudoplanar heterojunction (PPHJ) structure with favorable verticalstratification is devised via printing method. The pre-deposited D18-Cl regulatesmolecular stacking and crystallization, further forming efficient carriertransport-collection channels and mitigating energy loss. Therefore, the optimized PPHJ devices perform excellent PCEs of 19.05% (100 nm), 17.33% (300 nm), 14.14% (4 cm2), showing great potential in production of stablelarge-area OSCs. image"]
