Supramolecular force-driven non-fullerene acceptors as an electron-transporting layer for efficient inverted perovskite solar cells.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fullerene derivatives are widely employed as efficient electron-transporting layers (ETLs) in p-i-n perovskite photovoltaics but face challenges in mitigating interfacial recombination losses and ensuring stable film morphology. Non-fullerene acceptors (NFAs), commonly utilized in organic photovoltaics, present a promising alternative to fullerene-based ETLs. Nevertheless, the suboptimal performance of NFA-based devices underscores the need for molecular engineering to tailor their properties. Herein, we develop two Y-type NFAs, Y-Phen and Y-CE, by substituting the benzothiadiazole core of Y6 with higher-polarity phenanthroline and crown ether. These modifications effectively enhance carrier kinetics by (1) promoting ordered molecular assembly on the perovskite surface through supramolecular interactions, thereby optimizing interfacial energetic alignment, and (2) improving the molecular packing to facilitate efficient charge transport. Using Y-CE as the ETL, the device achieves a certified power conversion efficiency (PCE) of 25.59%. Furthermore, the optimized device exhibits less than 10% degradation in PCE after 1440 hours of thermal aging. This work offers valuable insights into designing NFA-based ETLs for high-performance perovskite photovoltaics.
