摘要（英）：

The invention relates to a mixed multilayer film structure of a solar cell. The mixed multilayer film structure comprises a silicon substrate, wherein a SiNx film is arranged on the silicon substrate; the mixed multilayer film structure is characterized in that a silicon oxide or silicon oxynitride film is arranged on the SiNx film; the SiNx film comprises a high refractive index SiNx film and a low refractive index SiNx film, which are sequentially arranged on the silicon substrate; the refractive index of the SiNx film is 2.0-2.3; the refractive index of the high refractive index SiNx film is 2.1-2.3; and the refractive index of the low refractive index SiNx film is 2.0-2.1; and the refractive index of the silicon oxide or silicon oxynitride film is 1.6-2.0. According to the mixed multilayer film structure, the antireflection effect of a cell coating is improved; light absorption is increased; and the short-circuit current of the cell is improved, so that the efficiency is improved, and the mixed multilayer film structure can be relatively well matched with a component EVA and glass.
