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

Scalable manufacturing of high-efficiency perovskite solar cells (PSCs) requires blade coating not only of the perovskite layer, but also of other functional layers, including organoammonium halide surface passivation layers and self-assembled monolayers (SAMs), under ambient conditions. However, organoammonium iodides and SAMs are highly hygroscopic and prone to hydrolysis and desorption, respectively, and they are commonly processed from hygroscopic alcohol. As a result, despite its importance for scalable production, ambient blade coating of these moisture-sensitive interfacial layers has rarely been demonstrated. Here, we report a general low-hygroscopic solvent system for blade coating hygroscopic organoammonium halides and SAMs. We mix alcohol with low-polarity alkane, where the alcohol dissolves the functional materials and the alkane suppresses moisture uptake during the blade-coating process under ambient conditions. Comprehensive chemical and optoelectronic characterizations confirm that low-hygroscopic solvent system is a general approach to blade coat both passivation layers and SAMs under high humidity. The devices with air blade-coated SAMs, perovskite, and passivation layers achieve a certified efficiency of 26.1% with negligible decrease even fabricated at 80% relative humidity. This work solves one of the most challenging issues of scalable fabrication of perovskite photovoltaics in ambient air.
