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

Incorporating polymer additives into hybrid perovskite solar cells is an effective strategy to enhance stability while retaining high efficiency. This study examines the impact of three polymers: polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), and polyvinyl alcohol (PVA) added at varying concentrations on the stability of perovskite as the absorber layer. Structural, optical, and electrochemical analyses demonstrate that adding PEG 0.3 mg/ml significantly improves perovskite films' morphology, light absorption, and charge transport while reducing recombination losses and enhancing long-term stability. Specifically, at room temperature and 30% relative humidity, the optimized perovskite sample with 0.3 mg/mL PEG maintained stability for up to 1000 h. Additionally, The UV analysis determined the band gap to be 1.58 eV. The electrochemical impedance spectroscopy analysis evaluated the charge transfer resistance (Rct) to be 1408 Ωcm², lower than other samples modified with polymer. The findings reveal that polymer modification significantly enhances the stability and efficiency of perovskite solar cells, improving their reliability and market competitiveness.
