Harmonious Layer Design in Wide-Bandgap p-i-n Perovskite Solar Cells Using Carbazole and Triazatruxene-Based Molecules.
Article in Small (Weinheim an der Bergstrasse, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Recent advancements in self-assembled monolayer (SAM) molecules have enhanced device efficiency and stability in wide-band gap perovskite solar cells (PSCs). Although numerous mixed SAM strategies enhance hole extraction, comprehending the morphology of surfaces with two or more different deposited SAMs remains challenging. Contact angle analysis is employed to understand the SAM ratio and correlate it with device efficiency. A harmonious layer for the perovskite bottom interface is designed by integrating tripodal 3PATAT-C3 and monopodal Me-4PACz, thereby improving wettability and hole extraction. This layer promotes π-π stacking, enhancing perovskite crystallization quality and reducing strain. Consequently, PSCs with a harmonious layer retain 91% of their initial performance after 2000 h, with an open-circuit voltage of 1.22 V and a fill factor of 84.1%. The study presents a novel approach for optimizing SAMs to achieve effective hole transport and reduced nonradiative recombination while ensuring a high-quality deposited interface.
