Abstract Large‐area printing fabrication is a distinctive feature of organic solar cells (OSCs). However, the advance upscalable challenged by thickness active layers considering importance both exciton dissociation and charge collection. In this work, bulk‐heterojunction‐buried (buried‐BHJ) structure introduced sequential deposition to realize efficient collection, thereby contributing OSCs with 500 nm thick layers. The buried‐BHJ distributes donor acceptor phases in vertical direction as transport channels, while numerous BHJ interfaces are buried each phase facilitate simultaneously. It found that configurations possess rapid transport, resulting reduced recombination losses. comparison traditional structures, displays decent tolerance film thickness. particular, power conversion efficiency 16.0% achieved at nm. To best authors’ knowledge, represents champion OSCs.

Abstract 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, desired and controllable pseudo planar heterojunction (PPHJ) structure with suitable phase separation developed by pre‐deposited D18‐Cl under PM6:BTP‐eC9 film via eco‐friendly manufacturing method. The addition of regulates molecular crystallization leads to ideal stratification while simultaneously suppressing voltage loss, optimizing energetic disorder, carrier management. Impressively, optimal PPHJ devices perform superior power conversion efficiencies (PCEs) 19.05% (100 nm), 17.33% (300 14.14% (4 cm 2 ) compared BHJ devices. Importantly, OSCs also exhibit impressive extrapolated T 80 (the time required reach 80% initial PCE) long‐time storage operational stability, as well thermal stability.

Abstract Semi‐transparent organic solar cells (ST‐OSCs) possess significant potential for applications in vehicles and buildings due to their distinctive visual transparency. Conventional device engineering strategies are typically used optimize photon selection utilization at the expense of power conversion efficiency (PCE); moreover, fixed spectral range always imposes an unsatisfactory upper limit its light (LUE). Herein, a novel solid additive named 1,3‐diphenoxybenzene (DB) is employed dual‐regulate donor/acceptor molecular aggregation crystallinity, which effectively broadens response ST‐OSCs near‐infrared region. Besides, more visible allowed pass through devices, enables satisfactory photocurrent high average transmittance (AVT) simultaneously. Consequently, optimal ST‐OSC based on PP2+DB/BTP‐eC9+DB achieves superior LUE 4.77%, representing highest value within AVT 40–50%, also correlates with formation multi‐scale phase‐separated morphology. Such results indicate that can simultaneously meet requirements minimum commercial plant photosynthesis when integrated roofs agricultural greenhouses. This work emphasizes significance additives tune ST‐OSCs, charts way photovoltaics economically sustainable development.
