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

The bulk photovoltaic effect (BPVE) in polar crystals offers a promising way to surpass the energy-conversion limits of conventional p-n junction devices. In layered materials, BPVE is typically dominated by an out-of-plane component. However, strong in-plane performance is essential for planar photovoltaics, requiring innovative strategies to overcome fundamental material constraints. In this study, an innovative pressure-induced emergence of in-plane BPVE is demonstrated in the planar-nonpolar layered bulk semiconductor γ-type indium selenide. External pressure distorts the lattice and breaks the intrinsic threefold rotational symmetry, triggering in-plane photovoltaic responses that are otherwise symmetry-forbidden at ambient pressure. Furthermore, the in-plane BPVE shows a distinctive crystallographic orientation dependence: the photocurrent is significantly higher along the armchair direction than along the zigzag direction, with a large anisotropy ratio of up to 280 observed at 0.16 GPa. Experimental characterization and first-principles calculations reveal that pressure lifts the symmetry-protected planar nonpolarity, reconstructing the electronic structure and activating a sizable in-plane shift-current response that is forbidden at ambient pressure. More broadly, this work establishes symmetry engineering through pressure as a general strategy for achieving large in-plane bulk photovoltaic responses in layered systems, without relying on material nanostructuring or interfacial design.
