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

Phase segregation is an inevitable phenomenon in wide-bandgap perovskites, triggering nonradiative recombination and degrading device performance. Herein, we propose a molecular-extrusion-driven passivation strategy by introducing bromomethyl-triphenylphosphonium bromide (TPB-Br) into perovskite precursors to achieve halogen homogenization. This approach simultaneously passivates bulk and interfacial defects, significantly mitigates phase segregation, and suppresses nonradiative recombination in wide-bandgap perovskites. As a result, we realize high-quality wide-bandgap perovskite films with high crystallinity, low defect density and released residual strain. Champion devices based on these films deliver impressive power conversion efficiencies (PCEs) of 23.63% in the 1.68 eV perovskite sub-cell and 32.03% (1.05 cm
