The invention discloses solid-state electrolyte for a dye-sensitized solar cell, and a preparation method of the solid-state electrolyte. The quasi solid-state electrolyte for the dye-sensitized solar cell is prepared from a three-dimensional net-shaped electrospun polymer fiber membrane, and nano-silicon dioxide and ionic liquid which are loaded on the electrospun polymer fiber membrane; when being used for the dye-sensitized solar cell, the nano-silicon dioxide with a modification effect can be used to remarkably improve the photoelectric conversion efficiency. 本发明公开了用于染料敏化太阳能电池的固态电解质及其制备方法。本发明的用于染料敏化太阳能电池的准固态电解质，其包含三维网状的电纺聚合物纤维膜，以及负载于所述电纺聚合物纤维膜上的纳米二氧化硅和离子液体，纳米二氧化硅的修饰作用在用作染料敏化太阳能电池时显著提高了光电转化率。
