Simple CsI doping outperforms complex organic additives in carbon-based perovskite solar cells.
Article in Nanoscale advances, 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
Carbon-based hole-transport-layer (HTL)-free perovskite solar cells (C-PSCs) have emerged as promising candidates for commercialization, owing to their low cost, high stability, and simple device architecture. Nevertheless, the performance of C-PSCs is still limited by inconsistent perovskite film quality and high defect density. While cesium iodide (CsI) doping has been explored in perovskite systems, its application in HTL-free C-PSCs remains relatively underinvestigated and often yields only limited performance improvements, particularly in single-cation systems or with the aid of additional interlayers or additives. In this work, we report a facile yet effective strategy of incorporating CsI into MA/FA dual-cation perovskite films
