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

Despite the rapid progress of perovskite solar cells (PSCs) toward commercialization, perovskite layers are unstable and contain toxic lead. Encapsulation represents an efficient strategy for improving the stability of PSCs as well as suppressing lead leakage. However, the damage to encapsulation materials during outdoor applications inevitably deteriorates the packaging effect and increases lead leakage. Here we report a damage perception and rapid self-healing encapsulant consisting of alkoxy polyvinylimidazole bis(trifluoromethanesulphonyl)imide (EP). The dynamic ion aggregates in the encapsulant can easily drive the molecular chain movement of EP, thereby achieving rapid damage repair to maintain device stability and inhibit lead leakage. The damaged cracks of EP completely self-heal within 6 minutes at 50°C. The EP encapsulated devices exhibit a lead sequestration efficiency of more than 99% under poor weather. After 1500 hours of damp heat test and 300 thermal cycles, the EP encapsulated devices retain 95.17 and 93.53% of their initial efficiency, respectively.
