NOVELTY - A hybrid electrode preparation method involves reacting polyethylene with ester sulfoxide to generate fluorinated polyethylene, and adding polyethylene purified water, 1-methyl imidazole, and N,N-dimethyl amide into resultant product. The resultant product is purified, and the purified product is dried at 120 degrees C to obtain fluoride molten salt as anion, and molten salt of low molecular weight polyethylene imidazole (I) as cation. The organic molten salt and nano stannic oxide gel are mixed and stirred to form gel electrolyte. The gel electrolyte is aged and purified to obtain finished product.    USE - Method for preparing hybrid electrode for dye-sensitized nanocrystalline solar cells.    ADVANTAGE - The method enables providing dye-sensitized nanocrystalline solar cells with high stability and conductivity.    DETAILED DESCRIPTION - A hybrid electrode preparation method involves preparing organic molten salt by reacting low molecular weight polyethylene with ester sulfoxide in the presence of pyridine to generate fluorinated polyethylene, adding polyethylene purified water, 1-methyl imidazole, and N,N-dimethyl amide into the resultant product and reacting at 85-95 degrees C for 48 hours. The resultant product is purified using ethanol, and the purified product is dried at 120 degrees C to obtain fluoride molten salt as anion, and molten salt of low molecular weight polyethylene imidazole as cation, where polyethylene imidazole cation has structure of formula (I).    n= 9-14;    R=H, OH, OCH3, CH2=CHCOO-, CH2=CCH3COO-.    . The polyethylene has molecular weight of 450-550. The organic molten salt and nano stannic oxide gel are doped at 80-90 degrees C, where the nanobismuth stannic oxide gel is prepared by mixing nanometer tin oxide powder and polyvinyl alcohol in a mass ratio of 1:1, adding nitric acid with concentration of 1.5-8 mol/L into the mixture and stirring mixture for 30 minutes to prepare acidic mixed salt solution. Ammonia water solution with concentration of 5-10.8 mol/L is added into the acidic mixed salt, followed by adjusting pH value to 5-7 under a poignant mill, controlling reaction temperature at 0-10 degrees C and stirring time for 30 minutes, and performing polymerization reaction at 80-280 degrees C to form a stable solid gel. The resultant organic molten salt and nano stannic oxide gel are mixed in a volume ratio of 50:7-15. The mixture is stirred continuously till the nano stannic oxide gel is completely dissolved, followed by preserving the mixture under heat for 6-8 hours to form gel electrolyte. The gel electrolyte is preserved under heat at 90-100 degrees C, followed by stirring to form uniform gel electrolyte, where electric conductivity of the gel electrolyte is 15.3-18.7 mS/cm, aging and purifying the gel electrolyte, cooling, sealing and storing to obtain finished product.
