▎ 摘　　要

NOVELTY - Preparing hierarchical graphene substrate of zinc oxide arrays involve carrying out non-hierarchical zinc oxide nano-catalytic chemical vapor deposition growth of graphene nanosheet on substrate. The graphene nanosheet is spin-coated on silicon or sapphire substrate. USE - Method for hierarchical graphene substrate of zinc oxide arrays used for preparing zinc oxide-based ultraviolet photo-detectors, zinc oxide based light-emitting diode devices and zinc oxide hybrid solar cell devices (all claimed). ADVANTAGE - The method enables to prepare hierarchical graphene substrate of zinc oxide arrays that is flexible, and has high efficiency and high performance.
