Moiré Perovskite Photodetector toward High‐Sensitive Digital Polarization Imaging (Adv. Energy Mater. 29/2021)

Moiré Perovskite Photodetectors In article number 2100742, Mingzhu Li and co-workers design and fabricate moiré perovskite photodetectors (PVK PDs) realizing sensitive polarization imaging by imprinting with a commercial DVD disc. The light-harvesting ability is boosted by coupled reflection, grating diffraction and excitation of waveguide modes, achieving high device responsivity (15.62 A W−1) and detectivity (5.58 × 1013 Jones).
