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

Perovskite/organic tandem solar cells are a promising strategy to surpass the efficiency limits of single-junction devices, yet their performance is restricted by recombination losses in the organic subcells. Here, we investigate these losses by tracking film evolution from the very initial stage of organic film formation. We strategically manipulated donor and acceptor ratios to modulate film growth characteristics, while employing in situ techniques to monitor the real-time crystallization dynamics. Our research findings underscore that the variance in donor content within the organic blend exerts a fine-tuning effect on the solution-to-solid transformation process. When the donor content is inadequate, the acceptor molecules tend to aggregate, disrupting molecular packing and lowering crystallinity. These morphological changes hinder exciton dissociation, thereby leading to charge recombination and deteriorating overall device performance. Optimizing film morphology and crystallization reduces recombination losses, enabling perovskite/organic tandem solar cells with a record 26.42% power conversion efficiency.
