Dye-sensitized solar cell counter electrode material and manufacturing method thereof

The invention discloses a manufacturing method for a dye-sensitized solar cell counter electrode material. The manufacturing method comprises the following steps: (1) performing ultrasonic dispersion on a grapheme oxide (GO) aqueous solution, and performing ozonation on the grapheme oxide (GO) aqueous solution to obtain a further oxidized grapheme oxide suspension liquid; (2) heating ethidene diamine and the oxidized grapheme oxide suspension liquid obtained in the step (1) in a closed container, heating in a oil bath pan at the temperature of 90-100 DEG C for 5-7 hours, purifying the obtained products to obtain ethidene-diamine-functionalization grapheme (EFG); (3) and mixing the products obtained in the step (2) with right amount of binder, grinding for 20-40 min to obtain a counter electrode slurry, using a knife coating method to coat the slurry on FTO conductive glass, and drying the glass. The manufacturing method for the cell counter electrode material is mild in reaction conditions, low in cost, simple in operation, and easy in commercialized popularization. The dye-sensitized solar cell counter electrode material is relatively high in photoelectric conversion efficiency after being assembled in a dye-sensitized solar cell.
