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

Perylene diimide (PDI)-based electron-transport layers (ETLs) are fundamental in governing charge extraction, interfacial recombination, and the operational longevity of organic solar cells (OSCs), yet their molecular design still lacks transferable principles. Here we present a PDI-ETL molecular design framework that couples bay-position engineering with polar, bulky side-chain modulation to improve additive-free alcohol solubility, suppress over-crystallization, and mitigate oxidative degradation. With this framework, H75-DMA suppresses reactive-oxygen-driven chemical evolution and interfacial trap accumulation, thereby stabilizing interfacial energetics and electron transport. Binary OSCs based on H75-DMA achieve a power conversion efficiency (PCE) above 20% and exhibit improved mechanical toughness and bending durability in flexible devices. Its smooth, high-surface-energy interface also induces continuous growth of ultrathin metal cathodes, leading to increased light-utilization efficiency in flexible semitransparent OSCs. In addition, H75-DMA enables cathode substitution from Ag to Cu while retaining about 97% of the PCE of the Ag-based devices, thereby improving cost-effectiveness at the device level.
