Abstract

The invention provides an optical anti-reflection structure, comprising a relief surface structure and a nano columnar structure located on the relief surface structure. Furthermore, the invention discloses a solar battery containing the optical anti-reflection structure, and a manufacturing method of the optical anti-reflection structure.

Description

technical field [0001] The present invention relates to an anti-reflection structure, and in particular to an anti-reflection structure of a multilayer nanostructure. Background technique [0002] Solar cells have been around 60 years since Bell Labs started using silicon doped with impurities. Today, solar cells have been widely used in all aspects of daily life. At present, the mainstream solar cells on the market are mainly crystalline silicon, which has been developed for a long time. Among them, monocrystalline silicon solar cells have the highest photoelectric conversion efficiency because of their small crystal defects and low electron-hole recombination. [0003] The photoelectric conversion efficiency of crystalline silicon solar cells is about 18%, but silicon has a reflectivity as high as 37.5% for sunlight, and this high reflectivity is one of the important factors causing the low efficiency of solar cells. In addition to the application of solar cells, there a...
