▎ 摘　　要

NOVELTY - The detector has a flexible transparent substrate layer (1) sequentially overlapped with a conductive anode layer (2), hole transport layer (3), active layer (4) and conductive cathode layer (5). The active layer is formed as a mixed film, which has a thickness of 800-1200 nm and is provided with an electron donor material and an electron acceptor material at 1:100-10:100 mass ratio. The conductive anode layer is made of indium-tin oxide material. USE - The flexible multiplication type organic photoelectric detector is used for wearable device. ADVANTAGE - The detector has high flexibility and small practical value, and adjusts mass ratio of the donor material and the acceptor material, uses small amount of donor material as electron trap under condition of reverse bias, and reinforces electron tunneling injection so as to achieve multiplication effect of multiplication type device, and has faster response speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the flexible multiplication type organic photoelectric detector comprising ultrasonically processing the transparent flexible substrate layer sequentially with deionized water, acetone, and isopropanol for 15 minutes, placing in vacuum drying box for drying, and continuously using UV light for 15 minutes to form a conductive anode layer; arranging a hole transmission layer on the conductive anode layer; dissolving the electron donor material and electron acceptor material in o-dichlorobenzene, magnetically stirring for more than 12 hours under shading condition to form mixed solution, preparing the mixed solution on the hole transport layer by spin coating, and annealing for 15 minutes at 130 degrees C to form active layer with thickness of 800-1200 nm; and providing conductive cathode layer on the active layer. DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of flexible multiplication type organic photoelectric detector.
