The invention belongs to the field of micro-nano manufacturing, and discloses a full-perovskite X-ray detector based on micro jet printing and a preparation method thereof, the full-perovskite X-ray detector comprises a substrate and an electrical interconnection structure, and any pair of first electrode unit and second electrode unit in the electrical interconnection structure is connected through an X-ray detection unit; the X-ray detection unit comprises a perovskite scintillator layer and a perovskite visible light sensitive layer which are arranged from top to bottom, and can detect X-rays. According to the invention, the structure and composition of the device are improved, the X-ray detection units distributed in an array manner are introduced by utilizing an electrical interconnection structure with a specific structural design, and the X-ray detection units are matched with the fluorescence spectrum of the scintillator and the sensitive wave band of the detector by integrating two different perovski
