摘要：
Perovskite materials，with their adjustable bandgaps，high light absorption coefficients，and low exciton binding energies，have shone brightly in the fields of semiconductor photovoltaics and photoelectric detection. The absorption range of universal lead-based perovskites is usually concentrated in the UV to Vis region，while the absorption spectra of narrow-bandgap pure tin-based or tin-lead mixed perovskites are still limited to the NIR range within ~1 060 nm，constrained by the application and detection imaging in future complex scenarios. Combining perovskites with narrow-bandgap semiconductors to construct“perovskite/semiconductor”composite heterostructures can further expand the spectral range and enhance absorption efficiency. This review summarizes the progress in optimizing detection performance，the exceptional properties of monomaterials，and the preferred engineering of composite materials for perovskite-based broadband photodetectors. It also discusses the advancements and application prospects of broadband detectors in terms of spectral response，pixel integration，development of flexible devices，and stability. This review aims to promote research in perovskite-based wide-band photodetection and its future imaging applications. © 2024 Editorial Office of Chinese Optics. All rights reserved.
