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

Fabricating high-performance perovskite solar cells (PSCs) with solution processing is conducive to low-cost commercial production, it is therefore rather critical to stabilize perovskite in both solution and solid phases. For this purpose, the speed-up ageing of perovskite solution in air was systematically studied and its severe spontaneous degradation was observed. To address this issue, we introduce 4-(trifluoromethyl) phenylhydrazine (TFPH) to modify the perovskite solution, which presents enhanced storage stability. Consequently, when the modified solution was used to prepare PSCs, we obtained much improved and well consistent power conversion efficiencies (PCEs, ~ 26.0%) regardless of the perovskite solution ageing time, as well as exciting operational stability, which maintains PCE ≥ 92% for 1830 hours. These results are attributed to TFPH's multifunctionality: a) hydrazine groups inhibit perovskite decomposition by dual-pathway mechanism; b) trifluoromethyl boosts dipole moment, aiding crystallization and strain relaxation; c) impurity reduction and high-quality film jointly lower charge traps. This work substantially assists understanding and modifying perovskite degradation in both solution and solid phases. The developed performance stability and consistency on the TFPH modified device batches is of great significance for commercial production of PSCs.
