PURPOSE: A dye compound, a dye-sensitive solar cell with high photoelectric conversion efficiency using the same, and a dye solution are provided to increase efficiencies of dye-sensitized solar batteries. CONSTITUTION: A dye compound or salt thereof has a structure of chemical formula (I). In the chemical formula (I), R1 and R2 independently indicate H, C1-12 alkyl, C1-12 alkoxy or halogen. D1 and D2 can independently indicate C1-12 alkyl, or D1, D2 and N indicate one which is formed from a functional group of chemical formula 1-a, functional group of chemical formula 1-b and functional group of chemical formula 1-c. The dye-sensitized solar cell comprises a photoanode including dye-compound having the structure of the chemical formula (I) or salt thereof, a cathode, and an electrolyte layer arranged between photocathode and anode. |
