Localized 2D/3D heterojunction enhances photovoltage for perovskite-organic tandem solar cells.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Wide-bandgap perovskite solar cells are essential for constructing multi-junction solar cells; nevertheless, their achievable photovoltage is often limited by non-radiative recombination losses caused by defect states, mismatched energy levels, and poor contact at interfaces, resulting in a photovoltage plateau beyond 1.68 eV. Here, we explore intricate Lewis acid-base interactions between hole-selective self-assembled monolayer and ammonium ligands to engineer a localized 2D/3D perovskite heterojunction at the buried interface. This structure not only help reduce defect density but also facilitate charge extraction and templated perovskite crystallization without compromising the bulk optoelectrical properties of 3D perovskite. These resulted in 1.30, 1.38, and 1.42 V photovoltages for 1.68, 1.79, and 1.85 eV bandgap perovskite solar cells, respectively, all exceeding 90% of their thermodynamic limits. We also demonstrate high-efficiency monolithic tandem solar cells by integrating the optimized wide-bandgap perovskite solar cell with an organic subcell to achieve a PCE of 27.11% (certified 26.3%).
