Chiral 1D perovskite microwire arrays for circularly polarized light detection

•Chiral 1D perovskite single-crystal microwire arrays are fabricated by using a capillary-bridge-manipulated method.•By the synergy of the excellent crystallinity and sensitive circular-polarization absorption leads to high-performance CPL photodetectors, with a maximum anisotropy factor of 0.23, responsivity exceeding 26 mA W − 1, and detectivity exceeding 2.2 × 1011 jones.•Microwire arrays present impressive environmental stability under ambient conditions for 30 days.
