Operando insights into stability of perovskite-based solar water splitting devices.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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-based solar water splitting systems are promising candidates for addressing environmental challenges, exceeding the commercialization efficiency of solar-to-hydrogen (STH) at >10%. However, the operational stability remains suboptimal due to insufficient in situ/operando insights into charge carrier dynamics. Here, we investigate the role of charge accumulation on operational stability through operando catalytic modulation via near-infrared (NIR) toggling on a photothermal catalyst. Electrochemical analyses under operando NIR toggling demonstrate enhanced hydrogen evolution reaction kinetics and reduced charge recombination. In situ analyses confirm that reduced charge accumulation suppresses ion migration in the perovskite layer, thereby enhancing operational stability. The NIR-irradiated cathode delivers a photocurrent density of 25.48 mA cm
