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

Overcoming the inherent limitations of perovskite-perovskite heterojunctions in simultaneously boosting built-in potential and suppressing non-radiative recombination remains a critical challenge in perovskite solar cells. Here, we introduce a ferroelectric-based heterojunction architecture that addresses this dual challenge through synergistic mechanisms. Firstly, the spontaneous polarization inherent to the ferroelectric-based heterojunction significantly amplifies the built-in electric field, enhancing charge separation and transport, thereby increasing open-circuit voltage from 1.16 to 1.21 V. Secondly, ferroelectric nuclei effectively regulate perovskite crystallization kinetics via dissolution-recrystallization modulation, effectively suppressing trap states and elevating fill factor from 83.6% to 86.8%. The champion devices achieve a power conversion efficiency of 26.62% (certified 26.07%) with an open-circuit voltage-fill factor product of 1.05 V, reaching 90.3% of the Shockley-Queisser limit. Furthermore, the modified devices demonstrate enhanced operational stability with over 85% efficiency reservation after 500 h of maximum power point tracking, charting clear pathways towards high-performance photovoltaic cells.
