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

Reverse bias stability remains a critical challenge for inverted perovskite solar cells (PSCs). While self-assembled monolayers (SAMs) boost efficiency, their low breakdown voltages limit device reliability. Thick PTAA layer improves breakdown voltage but suffers from poor wettability and efficiency loss, with unclear effects on device reverse bias stability. Here, we use electroluminescence mapping to reveal the critical role of hole transport layer (HTL) uniformity in affecting device reverse bias stability, and poor uniformity of current HTLs causes spatial heterogeneity that is not able to block electron injection and leads to device breakdown under reverse bias. Based on our study, we develop a polymeric Poly-PhPACz HTL with high conductivity and good wettability, achieving a breakdown voltage comparable to PTAA while maintaining high efficiencies across varying thicknesses. Ambient blade-coated Poly-PhPACz PSCs achieve 26.1% efficiency and retain 92% performance after 1,800 hours of light soaking. Further optimization yields a high breakdown voltage of -14.3 V without sacrificing efficiency, offering a promising pathway for stable PSCs.
