The variation of the vertical component distribution can significantly influence photovoltaic performance organic solar cells (OSCs), mainly due to its impact on exciton dissociation and charge-carrier transport recombination. Herein, binary devices are fabricated via sequential deposition (SD) D18 L8-BO materials in a two-step process. Upon independently regulating spin-coating speeds each layer deposition, optimal SD device shows record power conversion efficiency (PCE) 19.05% for single-junction OSCs, much higher than that corresponding blend casting (BC) (18.14%). Impressively, this strategy presents excellent universality boosting devices, exemplified by several nonfullerene acceptor systems. mechanism studies reveal with preferred components possesses high crystallinity, efficient splitting, low energy loss, balanced charge transport, resulting all-around enhancement performances. This work provides valuable approach high-efficiency shedding light understanding relationship between distribution.

Abstract Recent advances in the power conversion efficiency (PCE) of organic solar cells (OSCs) have greatly enhanced their commercial viability. Considering technical standards (e.g., mechanical robustness) required for wearable electronics, which are promising application platforms OSCs, development fully stretchable OSCs (f‐SOSCs) should be accelerated. Here, a comprehensive overview f‐SOSCs, aimed to reliably operate under various forms stress, including bending and multidirectional stretching, is provided. First, requirements terms tensile cohesion/adhesion properties, summarized along with experimental methods evaluate those properties. Second, essential studies make each layer f‐SOSCs efficient discussed, emphasizing strategies simultaneously enhance photovoltaic properties active layer, ranging from material design fabrication control. Key improvements other components/layers (i.e., substrate, electrodes, interlayers) also covered. Lastly, considering that f‐SOSC research its infancy, current challenges future prospects explored.

Abstract The power conversion efficiencies (PCEs) of organic solar cells (OSCs) have improved considerably in recent years with the development fused‐ring electron acceptors (FREAs). Currently, FREAs‐based OSCs achieved high PCEs over 19% single‐junction OSCs. Whereas relatively synthetic complexity and low yield FREAs typically result production costs, hindering commercial application In contrast, noncovalently (NFREAs) can compensate for shortcomings facilitate large‐scale industrial by virtue simple structure, facile synthesis, yield, cost, reasonable efficiency. At present, based on NFREAs exceeded 15% are expected to reach comparable efficiency as Here, advances this review provide insight into improving performance particular, paper focuses effect chemical structures molecule conformation, aggregation, packing mode. Various molecular design strategies, such core, side‐chain, terminal group engineering, presented. addition, some novel polymer all‐polymer also introduced. end, provides an outlook developing efficient, stable, low‐cost achieving applications.
