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 solar cells (PSCs) have emerged as a promising next-generation photovoltaic technology owing to their exceptional optoelectronic properties. Nevertheless, defect states within perovskite films lead to significant non-radiative recombination and ion migration, which substantially constrain both the power conversion efficiency (PCE) and operational stability of the devices. In this work, a dual-functional benzimidazole-based ionic liquid (IL) additive, 1-phenyl-1H-imidazol-3-ium trifluoromethanesulfonate (PIT), was incorporated into the perovskite precursor solution to regulate the crystallization, passivate defect states, and stabilize the crystal structure. The PIT anion, possessing a strong electron-donating ability, exhibits strong defect passivation capability by interacting with Pb
