1 · What the graph read from it

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.

2 · The registry

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

Non-radiative energy loss remains a challenge in organic solar cells. Here we show that introducing bulky chlorobenzene moieties at the end of inner side chains yields two acceptor materials, Y6-2Cl and Y6-4Cl. The introduction of chlorobenzene groups enhances the solubility, while also boosting the photoluminescence quantum yield and inducing a distinct molecular packing mode in Y6-2Cl and Y6-4Cl. Rather than following the conventional three-dimensional network structure observed in Y-series acceptors, these materials form a highly ordered, array-like arrangement while maintaining excellent crystalline characteristics. This unique structural feature not only preserves high charge-transport properties but also optimizes aggregation behavior and morphology of the active layers. The D18:Y6-2Cl binary device demonstrates a PCE of 20.0%. The ternary device composed of D18:L8-BO:Y6-2Cl achieves a PCE of 20.92%, accompanied by a fill factor of 82.93%. Overall, the side-chain functionalization strategy proposed in this study offers a direction for developing high-performance non-fullerene acceptors.
