DETAILED DESCRIPTION - Dinitrogen fluorine ligands-containing ruthenium dyes of formula (I) are new.    Y1, Y2 = monovalent ions of H, Li, k, or equivalent multivalent ions;    R0 = H, alkyl, cycloalkyl, aralkyl (derivatives), aryloxy, alkoxy, alkylthio, alkyl selenyl, alkyl telluro, hydroxyl, carbonyl, halo, CH3((CH2)2OCH2)nCH2-O-CH3, or CH3((CH2)2OCH2)nCH2-O-CH2-CH3;and    n = greater than or equal to 0.    An INDEPENDENT CLAIM is included for dye-sensitized solar cells comprising a transparent base layer (1), a conductive layer (2), a photo-absorption layer (3), an electrolyte layer (6) and a counter electrode (7). The conductive layer, photo-absorption layer, electrolyte layer and counter electrode are connected in order between two transparent base layers. The photo-absorption layer comprises semiconductor nanoparticle layer (4) and a dye layer (5). The nanoparticle layers are connected to the conductive layer, while the dye layer is connected to the electrolyte layer. The transparent base layer is made of glass base or plastics particularly polyethylene glycol terephthalate, polyethylene naphthalate, polycarbonate, polypropylene, polyimide, triacetyl cellulose, or polyether sulfone. The conductive layer is tin indium oxide, tin fluorine oxide, zinc oxide-gallium oxide, zinc oxide-alumina, tin-base oxide, tin antimony oxide, or zinc oxide. The semiconductor nanoparticle of semiconductor nanoparticle layer is silicon, titanium dioxide, zinc oxide, tungsten oxide, niobium oxide, or titanium strontium oxide. The average particle diameter of the semiconductor nanoparticle is greater than 0-less than 50 nm. The dye layer comprises dinitrogen fluorine ligands-containing ruthenium dye. The electrolyte layer comprises iodine/lithium iodide electrolyte or ionic liquid, and an organic hole transport material. The ionic liquid comprises two parts of anion and cation. The anion is e.g. iodide, bromide, chloride, hexafluorophosphate, tetrafluoroborate, nitrate, chlorate, aluminum tetrachloride, or silicon hexafluoride (51 further anions given in the specification).
