▎ 摘　　要

NOVELTY - The photo-detector has a first flexible fiber substrate (1) whose surface is covered with a p-type graphene nano-sheet film layer (2). An n-type zinc oxide nano wire array layer (3) and fibrous electrodes are grown on the surface of the p-type graphene nano sheet film layer. The P-type graphene nano sheet thin film layer and the N-type zinc oxide nano wire array layer form a P-N nano hetero junction active layer, and the P-N nano hetero junction active layer is connected with a conductive fiber electrode (4) or a deposited fibrous transparent conductive film to obtain the flexible self-driven fiber UV photoelectric detector. The thickness of the n-type zinc oxide nano wire array layer is 0.7-2 mu . USE - Graphene/zinc oxide hetero-junction based flexible self-driven fiber UV photo-electric detector. ADVANTAGE - The detector uses graphene nano-film and zinc oxide nano-wire array to construct hetero-junction, and has high UV light absorption efficiency and excellent flexibility. The detector reduces the complexity of the wearable system circuit, reduces the device weight, improves the device portability and realizes low power consumption. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the flexible self-driven fiber UV photo-electric detector.
