TiO2 nanosheets coated SnO2 nanoparticle Dye-sensitized solar cells comprising the same and Method for Fabrication thereof

摘要

The present invention relates to a photoelectrode for a dye-sensitized solar cell and a dye-sensitized solar cell including the same, which utilizes a porous titanium dioxide thin film containing tin dioxide nanoparticles coated with a titanium dioxide nanosheet, Coated titanium dioxide nanoparticles and mesoporous titanium dioxide thin films containing the same exhibit the characteristics of tin dioxide which has high electron mobility to activate the migration of electrons and the coating of the titanium dioxide nanosheets enables tin dioxide to be exposed to the dye / And it has high surface area and electrochemical characteristics, which are characteristic of nanosheets. Therefore, it is possible to realize a more efficient dye-sensitized solar cell when it is used as a photoelectrode. In addition, the excellent electric scattering property of the nanotube can improve the light harvesting efficiency of the dye-sensitized solar cell. Such one-dimensional nanoparticles can be used to maintain the conventional titanium dioxide mesoporous structure, The long-term stability of the dye-sensitized solar cell can be improved by utilizing the efficient penetration of the polymer and the solid electrolyte.
