Anti-reflection micro-nano structure surface with protective structure and preparation method of anti-reflection micro-nano structure surface

The invention discloses an anti-reflection micro-nano structure surface with a protective structure and a preparation method of the anti-reflection micro-nano structure surface, relates to the field of micro-nano structures and manufacturing, and solves the problem that the micro-nano structures cannot be protected in the prior art. The surface comprises a substrate, a mesh structure and a micro-nano structure, the substrate and the micro-nano structure are of an integrated structure, and the mesh structure is arranged on the substrate; and the mesh structure is higher than the micro-nano structure. According to the invention, for the protection of various micro-nano structures and solar cells, the characteristics of damage resistance, pollution resistance and super-hydrophobicity are fundamentally realized microcosmically. The material of the structure can adopt but is not limited to an oxide layer, under the condition that the used material has certain hardness and the optical performance is suitable for th
