Atomic motion could help push solar cells beyond conventional limits

Дата публикации: 05-10-2026 20:20:16

The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this in CuCrP2S6, a van der Waals material that transitions from a noncentrosymmetric to a centrosymmetric average structure. The finding challenges the conventional view of BPVE and suggests a new strategy for enhancing photoelectric conversion.
