Particle decoration enables solution-processed perovskite integration with fully-textured silicon for efficient tandem solar cells.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Perovskite/silicon tandem solar cells can exceed Shockley-Queisser limit, but achieving complete coverage of 2-4 μm pyramids on industrial fully-textured silicon with solution-processed perovskite film remains challenging. We address this issue by spray-coating alumina particles onto fully-textured silicon, creating a super-hydrophilic rough surface that both enhances wet film coverage and provides guided nucleation sites. Although super-hydrophilic effect enhances wetting, it alone is insufficient to achieve complete coverage of pyramids by perovskite film. Beyond enhanced wetting, alumina particles promote uniform nucleation at particle-decorated sites across pyramids by lowering nucleation barrier and suppressing valley-preferred nucleation, which enables near-conformal deposition of perovskite film on pyramids. Additionally, alumina particles reduce nonradiative recombination and extend carrier lifetimes. Using this approach, we achieve a efficiency of 32.74% for perovskite/silicon tandem solar cells with one-step solution-processed perovskite on fully-textured silicon. This strategy offers a pathway for seamless integration of perovskite and silicon photovoltaics into high-performance tandem devices.
