Recent Advances in Halide Perovskite Photodetectors Based on Different Dimensional Materials

Abstract Based on the understanding and control of the energy levels and density of defect states of 0D, 1D, 2D, and 3D materials, halide perovskite photodetectors (HPPDs) based on different dimensional materials have recently gained significant achievements. In addition, the detection range of HPPDs even extended from ultraviolet–visible–near infrared (UV–vis–NIR) to X/γ photons, and the self‐powered HPPDs also became a hot issue. In this review, a comprehensive summary of the recent advances in HPPDs based on different dimensional materials is proposed, including 0D, 1D, 2D, and 3D perovskite and nonperovskite (without perovskite ABX 3 crystal structure) materials, focusing on the relationship among the charge‐carrier transport, operation mechanism, device architectures, and photodetecting performances. First, an introduction of composition and crystal structures of HPPDs is given, followed by the description of their key figure‐of‐merit parameters evaluation system. Next, the recent developments of HPPDs based on different dimensional materials are highlighted. And finally, the characteristics of HPPDs depending on the dimensionality are summarized, and the potential challenges and approaches for future study are also presented.
