NOVELTY - Preparing electrode of dye-sensitive solar battery at low temperature comprises: (a) preparing titanium dioxide anode paste; (b) preparing the thin film: coating the titanium dioxide anode paste as the film; drying; heating; cooling, immersing it into 0.5 mM of N3 dye absolute ethyl alcohol solution; taking it out and washing it using ethanol; and (c) packaging and testing: packaging the titanium dioxide thin film electrode and the platinum (Pt) paired electrodes using surlyn film; injecting the electrolyte on the Pt electrode; and testing photoelectric performance under the standard sunlight.    USE - The process is useful for preparing electrode of dye-sensitive solar battery at low temperature (claimed).    ADVANTAGE - The process improves the paste preparation technique to make up for the shortages of preparing paste using the P25-type titanium dioxide particles, reinforces the bridging action among the P25 particles, reduces the transmission resistance of the photoelectrons in the thin film, avoids the waste of time and energy of long-term high-temperature hydrothermal reaction, and further improves the light current of the battery.    DETAILED DESCRIPTION - Preparing electrode of dye-sensitive solar battery at low temperature comprises: (a) preparing titanium dioxide anode paste: preparing materials comprising titanium isopropylate, glycol, and glacial acetic acid with mol ratio of 1:3-10:3-20; heating glycol at 60 degrees C; during the mixing, dripping titanium isopropylate gradually; preserving the heat and mixing for 15 minutes; adding glacial acetic acid and heating at 90 degrees C; mixing for 10 hours or more to obtain the transparent sol; mixing the sol with the titanium dioxide particles based on the mass ratio of 1-10:1; and milling it using the high-performance ball mill to obtain the titanium dioxide anode paste for dye-sensitive solar battery; (b) preparing the thin film: coating the titanium dioxide anode paste obtained in (a) as the film; where the working area of the thin film is 1 cm2; and the thickness is 8-10 mu m; after naturally drying it; heating at 200 degrees C and preserving the heat for 15 minutes, heating at 250 degrees C and preserving the heat for 15 minutes, and heating at 540 degrees C and preserving the heat for 30 minutes; cooling at 80 degrees C, taking out the titanium dioxide electrode thin film; and immersing it into the 0.5 mM of N3 dye absolute ethyl alcohol solution; and placing it still for 24 hours; and taking it out and washing it using ethanol to remove the dye on the surface to obtain the titanium dioxide thin film electrode; and (c) packaging and testing: packaging the titanium dioxide thin film electrode and the platinum (Pt) paired electrodes using surlyn film with the thickness of 80 mu m; injecting the electrolyte from the small hole pre-left on the Pt electrode; and after packaging the hole, testing the photoelectric performance under the standard sunlight.
