NOVELTY - A dye sensitized solar battery counter electrode manufacturing method involves connecting a conductive substrate with a negative electrode of a power supply. The conductive substrate is removed using alcohol followed by washing using deionized water for 10 minutes, providing the conductive substrate to sodium borohydride aqueous solution, and soaking and reacting for 5-20 minutes at 40-70 degrees C. The conductive substrate is removed from the sodium borohydride aqueous solution followed by placing to a vacuum drying box for drying for 4-8 hours at 80-100 degrees C to obtain a counter electrode.    USE - Method for manufacturing a counter electrode of a dye sensitized solar battery.    ADVANTAGE - The method enables improving specific surface area of the counter electrode, and improving the catalytic performance of the counter electrode and photoelectric conversion efficiency of a dye sensitized solar battery. The utilization of a carbon nano-tube reduces manufacturing cost of the dye sensitized solar battery.    DETAILED DESCRIPTION - A dye sensitized solar battery counter electrode manufacturing method involves connecting a conductive substrate with a negative electrode of a power supply, and connecting a metal thin plate with a positive electrode of the power supply. The conductive substrate and the metal thin plate are arranged in a parallel manner at certain distance. Direct-current power supply is applied for performing electrophoresis deposition. The conductive substrate is removed using alcohol followed by washing using deionized water for 10 minutes, drying for 10-20 minutes at 80-100 degrees C, spraying chloroplatinic acid solution to the conductive substrate deposited a carbon nano-tube, providing the conductive substrate to sodium borohydride aqueous solution, and soaking and reacting for 5-20 minutes at 40-70 degrees C. The conductive substrate is removed from the sodium borohydride aqueous solution followed by placing to a vacuum drying box for drying for 4-8 hours at 80-100 degrees C to obtain a counter electrode.
