Dye-sensitized solar battery with sealing structure and preparation method thereof

The invention discloses a dye-sensitized solar battery with a sealing structure, which comprises conducting glass and a platinum electrode substrate, and an electrolyte is filled between the platinum electrode and the conducting glass. The conducting glass is printed with a plurality of silver grids, light anodes smaller than the silver grids are printed inside the silver grids, and the silver grids are coated with at least one layer of film with an injection hole. The film seals the silver grids, the electrolyte is filled between the film and the silver grids, and the platinum electrode substrate covers the film. Moreover, the injection hole is sealed by curing glue. Because of the combination of the film, the silver grids and the platinum electrode substrate in the structure, the probability that the electrolyte corrodes the silver grids and a packing material is reduced, so that the problems of volatilization and leakage of the electrolyte are finally avoided, the stability of the dye-sensitized ...
