Towards better solar cells: Exploring an anomalous phenomenon of electricity generation

Shinshu University
Peer-Reviewed Publication

The bulk photovoltaic (BPV) effect is an uncommon phenomenon that may enable certain materials to outperform the conventional p–n junctions used in solar cells. In a recent study, researchers from Japan have experimentally demonstrated the BPV effect in alpha-phase indium selenide (α-In₂Se₃) for the first time along the out-of-plane direction, validating previous theoretical predictions. The remarkable conversion efficiency recorded in their α-In₂Se₃ device signals a promising advancement for future solar cell technologies and photosensors.
