'Ion-freeze' efficiency in perovskite solar cells: time scales for ion immobilization.
Article in EES solar, 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
It is essential to shed light on the complex multiscale dynamics of mobile ions in perovskite solar cells for developing efficiency testing protocols, gaining a deeper understanding of the degradation mechanisms, improving long-term stability, and, ultimately, driving the commercialization of this technology. This study provides characteristic times for inhibiting the presence of mobile ions in efficiency measurements, enabling a comparison between 'ion-freeze' and steady-state efficiencies to quantify ion-induced degradation losses. Using current transient analysis during current-voltage measurements for a wide range of sweep rates, we achieve precise time-scale mapping of the complex ionic landscape of perovskites, spanning from ion immobilization (at time scales much shorter than the diffusion rate) to the equilibrium situation, encompassing the ubiquitous hysteresis effects for which we define a scan-rate range of occurrence. We corroborate the theory by using Impedance Spectroscopy. Our study provides valuable information about the intricate ionic dynamics in the context of classical current-voltage measurements, supporting the integration of these complementary experiments into the foundational characterization practices of the perovskite photovoltaic community.
