Self-driven radiation detector based on perovskite lamination

The invention belongs to the field of radiation detection, and particularly relates to a self-driven radiation detector based on perovskite lamination. The invention relates to a silver-bismuth-based organic-inorganic hybrid double perovskite solar cell and aims to achieve the purpose that silver-bismuth-based organic-inorganic hybrid double perovskite not only has an electron extraction effect, but also can isolate oxygen and moisture in the air and greatly prolong the service life of a device, and adopts the main scheme that the silver-bismuth-based organic-inorganic hybrid double perovskite solar cell sequentially comprises a substrate layer, a first electrode, a hole transport layer, an X-ray absorption layer, an electron transport layer and a second electrode from a bottom layer, an insulating protective layer; the first electrode fully covers the substrate layer, the hole transport layer, the X-ray absorption layer, the electron transport layer and the second electrode are arranged in sequence and then
