Abstract Developing efficient and stable all‐polymer solar cells (all‐PSCs) has received increasing attention because of their mechanical robustness for flexible devices. Based on the CH‐series small molecule acceptors, a new polymer acceptor (PZC24) is reported obtains decent power conversion efficiency (PCE) 16.82% when blended with PM6. To further improve performance, an oligomeric (CH‐D1), which possesses same backbone structure as PZC24, proposed synthesized third component all‐PSC system. The creative strategy improves crystallinity molecular packing, can maintain charge transport channels all‐PSCs binary Therefore, PM6:PZC24:CH‐D1 based ternary devices exhibit impressive PCE 17.40%, among highest value all‐PSCs. Compared to PM6:PZC24, device exhibits enhanced photosoaking stability thermal stability, simultaneously. In addition, introduction does not weaken As such, display excellent 15.35%. Importantly, this shows universality in PM6:PY‐IT PM6:PY‐V‐γ improved PCEs over 17%. results provide feasible simultaneously photovoltaic herald bright future

The ternary blend is demonstrated as an effective strategy to promote the device performance of organic photovoltaics (OPVs) due dilution effect. While compromise between charge generation and recombination remains a challenge. Here, mixed diluent for further improving efficiency OPV proposed. Specifically, high-performance system with polymer donor, i.e., PM6, nonfullerene acceptor (NFA), BTP-eC9, diluted by diluents, which involve high bandgap NFA BTP-S17 low BTP-S16 (similar that BTP-eC9). better miscibility BTP-eC9 can dramatically enhance open-circuit voltage (VOC ), while maximizes or short-circuit current density (JSC ). interplay BTP-17 enables recombination, thus leading 19.76% (certified 19.41%), best among single-junction OPVs. Further analysis on carrier dynamics validates efficacy diluents balancing be attributed more diverse energetic landscapes improved morphology. Therefore, this work provides commercialization.

Abstract Fullerene acceptors typically possess excellent electron-transporting properties and can work as guest components in ternary organic solar cells to enhance the charge extraction efficiencies. However, conventional fullerene small molecules suffer from undesirable segregation dimerization, thus limiting their applications cells. Herein we report use of a poly(fullerene- alt -xylene) acceptor (PFBO-C12) component enables significant efficiency increase 16.9% for binary 18.0% all-polymer Ultrafast optic optoelectronic studies unveil that PFBO-C12 facilitate hole transfer suppress recombination. Morphological investigations show blends maintain favorable morphology with high crystallinity smaller domain size. Meanwhile, introduction reduces voltage loss light stability mechanical durability flexible devices. This demonstrates introducing polyfullerenes is an effective approach achieving highly efficient good robustness.
