NOVELTY - The battery has a photo electrode connected to a counter electrode and coated with electrolyte. Electrolyte solution is filled between the counter electrode and the photo electrode. The counter electrode is coated with a seal material. A reflection layer is coated with the electrolyte solution. A photo-electrode side transparent substrate is a transparent inorganic substrate or transparent plastic substrate. A dyesensitized semi-conductor porous film is made of a semi-conductor material. Ionic solution is methyl propyl imidazole iodine. An electrode material film is coated with polar solvent.    USE - Dye-sensitized solar energy battery.    ADVANTAGE - The battery reduces energy loss. The battery has high photoelectric conversion efficiency, and is inexpensive.    DETAILED DESCRIPTION - The reflection layer is selected from a silver material and an aluminum material. The transparent inorganic substrate is made of quartz, sapphire or glass. The transparent plastic substrate is composed of a material that is selected from ethylene terephthalate, polyethylene naphthalate, polycarbonate, polypropylene, polyphenylene sulfide, polyvinylidene fluoride, polyimide, polysulfone and polyolefin. The battery adopts a photo-electrode side transparent electric conduction film that is composed of a material that is selected from indium tin composite oxide, tin dioxide and antimony doped tin dioxide. The semi-conductor material is titanium dioxide, magnesium oxide, zinc oxide, tin dioxide, tungsten trioxide, iron (III) oxide, niobium pentoxide, strontium titanate, barium titanate, zinc sulfide, cadmium telluride and indium phosphide. The electrode material film is composed of a material selected from platinum, gold, carbon or conductive polymer. The polar solvent is selected from acetonitrile, ethylene carbonate, propylene carbonate, gamma-butyrolactone, pyridine and dimethyl acetamide. The electrolyte solution is tertiary butyl pyridine, 1-methyl benzimidazole and alkyl carboxylic acid. The electrolyte is included with acid salt, metal bromide salt, ferrous cyanide iron acid, dicyclopentadienyl iron and lithium iodide or sodium iodide. The metal bromide salt comprises lithium, carbon steel, sodium, magnesium and calcium. The organic bromide salt is four alkyl ammonium ion, pyridine-type ion, imidazole ion or quaternary ammonium ion.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a dye-sensitized solar energy battery.
