NOVELTY - Electrolyte space layer of dye-sensitized solar cell is prepared by dipping fiber glass in absolute ethyl alcohol or acetone and dispersing the fiber glass using ultrasonic; and drying the fiber glass in an oven without changing the liquidity of electrolyte. The space layer is then prepared by laying the processed fiber glass on a counter electrode of solar cell; depositing encapsulating materials on edge of electrode; depositing work electrode on physical support layer of fiber glass; and encapsulating, pressing the solar cell, and filling the electrolyte.    USE - Method for preparing space layer of electrolyte for dye-sensitized solar cell (claimed).    ADVANTAGE - The method can simplify the preparation of the cell, ensure thickness of the space layer of electrolyte, improve yield and efficiency of cell by 10%, and prevent short circuit between the electrode structures caused by internal heat expansion and shrinkage of the cell; and is suitable for manufacturing large-area cell. The solar cell utilizing the space layer of electrolyte has good stability and improved mechanical strength, and ensures separation of the work electrode and the counter electrode as compared with a solar cell having space layer of electrolyte directly encapsulated.    DETAILED DESCRIPTION - Preparation of electrolyte space layer of dye-sensitized solar cell comprises selecting fiber glass with corresponding diameter according to thickness required by the space layer, where the selected fiber glass satisfies fire-resistant and electrolyte corrosion resistant requirement below 100 degrees C and the insulation requirement between the electrodes; dipping the fiber glass in absolute ethyl alcohol or acetone and dispersing the fiber glass using ultrasonic; and drying the fiber glass in an oven without changing the liquidity of electrolyte. The space layer is then prepared by laying the processed fiber glass on a counter electrode of solar cell; depositing encapsulating materials on edge of electrode; depositing work electrode on physical support layer of fiber glass; and encapsulating, pressing the solar cell, and filling the electrolyte. The solar cell comprises a conductive glass, a counter electrode, encapsulating materials, electrolyte, and work electrode sensitized by dyes. The electrolytes are encapsulated in the space layer between the counter electrode and the work electrode. The space layer of electrolyte is prepared with the fiber glass as the physical support.
