NOVELTY - Preparation of dye sensitization solar battery of double helix structure comprises precipitating titanium source with natural or alkaline hydrolysis reaction liquid in water, peptizing, and standing for 10-15 hours; and ultrasonic processing spiral titanium (Ti) positive electrode via alcohol and acetone, polishing spiral Ti via sand paper, immersing in chloroplatinic acid hexahydrate solution for electrofacing, connecting prepared light positive electrode and negative electrode, placing in glass tube with electrolyte, and sealing by sealing rubber.    USE - Method of preparation of dye sensitization solar battery of double helix structure (claimed).    ADVANTAGE - The method prepares dye sensitization solar battery having long stability of dye-sensitized solar cell battery and use rate of solar energy on light can be effectually improved, exerts good low light level characteristic, and is suitable for industrial production.    DETAILED DESCRIPTION - Preparation of dye sensitization solar battery of double helix structure comprises precipitating titanium source with natural or alkaline hydrolysis reaction liquid in water to obtain white titanium hydroxide precipitate, washing white titanium hydroxide precipitate, and peptizing at 30-80 degrees C with titanium (Ti4+), organic acid, hydrogen peroxide at mol ratio of 1:2-10:2-10, and standing for 10-15 hours to obtain titanium dioxide collosol precursor liquid; respectively ultrasonic processing spiral titanium (Ti) positive electrode via alcohol and acetone, heating water processing for 12-72 hours at 70-250 degrees C, hot processing at 200 degrees C for 4 hours to obtain pre-treated light positive electrode plated with titanium dioxide, immersing pre-processed light positive electrode in dye for 2 hours, washing surface dye via absolute ethyl alcohol to obtain light positive electrode; and polishing spiral Ti via sand paper, respectively processing via alcohol and acetone, immersing in chloroplatinic acid hexahydrate solution for electrofacing, spraying silica solution for isolation treatment after finishing, processing at 150 degrees C for 30 minutes to obtain negative electrode, connecting prepared light positive electrode and negative electrode, placing in glass tube with electrolyte, screwing glass tube upper cover, and sealing by sealing rubber.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the preparation of dye sensitization solar battery of double helix structure.
