PREPARATION METHOD FOR 3-DIMENSIONAL MESOPOROUS TIO2 ELECTRODES USING ORGANIC-INORGANIC HYBRID TEMPLATES AND DYE-SENSITIZED SOLAR CELLS USING THE SAME CAPABLE OF IMPROVING ENERGY CONVERSION EFFICIENCY

摘要

PURPOSE: A preparation method for 3-dimensional mesoporous TiO2 electrodes using organic-inorganic hybrid templates and dye-sensitized solar cells using the same are provided to improve the long-term stability of a solar cell using the penetration of an electrolyte.;CONSTITUTION: A hybrid alumina composite disperses throughout a solvent to manufacture a supporter solution. A sol solution and the supporter solution are mixed to manufacture a sol mixture. A composite thin film of titanium dioxide and alumina is manufactured by a high temperature sintering process. The alumina of the composite thin film is selectively removed.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Ti precursor/H2O/HCl; (BB) Grafting of a polymer and alumina; (CC) Polymer grafted alumina/solvent; (DD) Drop casting/high temperature sintering; (EE) Selective removal of the alumina in strong acid/strong basicity; (FF) TiO2 film with a mesoporous structure;
