Amplified narrowband perovskite photodetectors enabled by independent multiplication layers for anti-interference light detection.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Metal-halide perovskite narrowband photodetectors offer a low-cost opportunity to detect specific signals covering a broad spectrum directly. However, the thickness of charge collection narrowing mechanism photodetectors increases recombination, resulting in performance bottlenecks. Here, we demonstrate amplified narrowband photodetectors that combine perovskite single-crystal absorbers and organic multiplication layers. The separation of the multiplication layer controls the density of trap states while amplifying the response of conventional narrowband photodetectors by more than 215 times. The carrier dynamics were characterized by ultrafast measurement, thus verifying the mechanism of response amplification. By analyzing multiplication with different trap states energy levels under charge injection, it is shown that dopants have a wide selection space, providing a feasible path for high-performance narrowband photodetectors. As a result, the external quantum efficiency of 2259% with a 38-nanometer full width at half maximum and the specific detectivity of 4.84 × 10
