Assessing the Opportunities of Spectral Shaping by Quantum Cutting for Perovskite/Silicon Tandem Solar Cells.
Review in ACS energy letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Quantum cutting using Yb-doped halide perovskites provides a promising route for reshaping the solar spectrum for perovskite/silicon tandem photovoltaics by converting one high-energy ultraviolet or visible photon into two near-infrared photons. Using detailed balance analysis, we find that the idealized efficiency limit of perovskite/silicon tandem solar cells remains largely unchanged but identify several opportunities for using a quantum cutting layer. Integrating such a layer shifts the optimal top cell bandgap from 1.7 to ∼1.45 eV, opening the possibility of using potentially more stable, neat iodide perovskite compositions without sacrificing performance. Additionally, beyond efficiency, quantum cutting layers could mitigate ultraviolet-induced degradation of the solar cell stack. Finally, we identify key areas of research needed to unlock this spectral reshaping strategy.
