The invention discloses a flexible dye-sensitized solar cell and a manufacturing method thereof. The flexible dye-sensitized solar cell comprises an electrolyte layer, a flexible photocathode layer combined with the electrolyte layer, a flexible photoanode and dye layer combined with the electrolyte layer. The manufacturing method of the flexible dye-sensitized solar cell comprises the steps of manufacturing the flexible photocathode layer, manufacturing the flexible photoanode and the dye layer, manufacturing the electrolyte layer, and packaging the cell. By replacing traditional conductive glass with a flexible conductive film, the complete flexibility of the dye-sensitized solar cell can be achieved, the electronic transmission can not be affected in the case that the cell is bent, thecarrying and installation of the cell are convenient, the manufactured solar cell has the semitransparent effect, and thus, the application fields of the solar cell is greatly enlarged.
