Lattice expansion of hybrid perovskite inhibits halogen interstitial generation and enhances solar cell performance.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
One of the primary challenges for halide perovskite technology lies in its instability. Water is a ubiquitous environmental factor known to induce lattice expansion to perovskite. Lattice expansion has been proven beneficial to perovskite solar cell, but little is known about its role in lattice stability. In this work, we expose perovskites with pre-adsorbed water to vacuum and investigate the evolution of their structure. Our results show that vacuum induces water desorption and results in the removal of lattice expansion. This lattice recovery leads to an increasing lattice distortion, ultimately favoring the formation of halogen trimers in the case of hybrid perovskites. We thus find that the lack of lattice expansion facilitates the generation of defects detrimental to hybrid perovskite devices. Here, we report the crucial role of lattice expansion in preventing degradation of hybrid halide perovskites, which is of critical importance in the context of solar cell fabrication.
