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

Because perovskite films degrade quickly in humidity conditions, perovskite solar cells (PSCs) prepared in ambient air still show lower photovoltaic performance than those prepared in an inert atmosphere. Here, we offer an effective interfacial passivation method via a poly(N-vinylcarbazole) (PVK) layer to protect perovskite films and prevent their moisture degradation under ambient air conditions. The power conversion efficiency of the PVK-based champion PSC is 23.27% and is higher than that of the control PSC (20.94%). Meanwhile, the PVK-based perovskite films exhibit a large water contact angle, which is attributed to the hydrophobic nature of the uniformly deposited PVK layer. This leads to no significant effect for the PVK-based perovskite film with moisture degradation for 6 days under an RH of 50%, and the corresponding PVK-based PSC exhibits a higher efficiency of 21.64% and a smaller hysteresis index. Moreover, even after 3550 h of storage in an argon glovebox, the PVK-based PSC retains 98% of its initial efficiency.
