TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: In manufacturing the dye-sensitized/ligand-to-metal charge-transfer hybrid solar cell, the salicylic acid derivative is represented by Formula 1.X1-X4=each independently selected from a hydrogen atom, a heavy hydrogen atom, a halogen atom, a hydroxy group, a cyano group, a nitro group, an alkenyl group of 2-30 carbon atoms, a substituted or unsubstituted condensed aromatic ring of 10-60 carbon atoms, a substituted or unsubstituted styryl group, a substituted or unsubstituted amino group, a substituted or unsubstituted carbonyl group, a substituted or unsubstituted carboxyl group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted cycloalkyl group of 3-40 carbon atoms, a substituted or unsubstituted cycloalkenyl group of 3-40 carbon atoms, a substituted or unsubstituted alkoxy group of 1-60 carbon atoms, a substituted or unsubstituted silyl group of 3-40 carbon atoms, a substituted or unsubstituted straight-chain, branched-chain or cyclic alkyl group of 1-60 carbon atoms, a substituted or unsubstituted aryl group of 6-60 carbon atoms, a substituted or unsubstituted aralkyl group of 7-60 carbon atoms, a substituted or unsubstituted heteroaryl group of 3-40 carbon atoms, and a substituted or unsubstituted heteroaralkyl group of 4-40 carbon atoms, where X1-X4 are each independently substituted by one or more substituent groups selected from a hydrogen atom, a heavy hydrogen atom, a halogen atom, a cyano group, a nitro group, an alkyl silyl group of 1-10 carbon atoms, an alkyl group of 1-40 carbon atoms, an alkoxy group of 1-40 carbon atoms, an alkylamino group of 1-40 carbon atoms, an aryl group of 6-30 carbon atoms, an aryloxy group of 6-30 carbon atoms, an aryl amino group of 6-30 carbon atoms, an aryl silyl group of 6-30 carbon atoms, and a heteroaryl group of 3-40 carbon atoms.The salicylic acid derivative is any one selected from 4-hydroxy-7-trifluoromethyl-3-quinolinecarboxylic acid, 3-hydroxy-2-quinoxalinecarboxylic acid, 2-hydroxy-5-(1H-pyrrol-1-yl)benzoic acid, 3-hydroxypicolinic acid, 2-(4-hydroxyphenylazobenzoic acid), 2-hydroxynicotin acid, 3-hydroxy-2-naphthoic acid, 2-hydroxy-l-naphthoic acid, 1-hydroxy-2-naphthoic acid, 3-hydroxy-2-methyl-4-quinolinecarboxylic acid, 2-hydroxy-6-methylpyridine-3-carboxylic acid, and 2-hydroxy-3-isopropylbenzoic acid. The organic solvent is selected from ethanol, methanol, propanol, isopropanol, and acetonitrile. The dye is a ruthenium-based dye. In the working electrode of the dye-sensitized/ligand-to-metal charge-transfer hybrid solar cell, the ligand is selected from salicylic acid, a salicylic acid derivative, catechol, salicylaldehyde, saccharine, salicylamide, 1,4,5,8-naphthalenetetracarboxylic acid, anhydrous 1,4,5,8-naphthalenetetracarboxylic acid, anhydrous 1,8-naphthalic acid, 1-naphthoic acid, naphthol blue black and naphthol green B. Preferred Parameters: The dye solution is prepared by dissolving 5-95 wt.% of the dye and 5-95 wt.% of the compound in the organic solvent. EXAMPLE - No suitable example given.
