Ru-type dye is provided to show remarkably improved photoelectric transformation efficiency compared to the existing dye, to strengthen bonding force with titanium dioxide, and to enusre excellent Jsc(short circuit photocurrent density) and molar absorption coefficient, thereby largely improving the efficiency of solar cell. Ru-type dye is represented by the following chemical formula 1, wherein al ring is optionally substituted by one or more substituent selected from the group consisting of halogen atom, amide, cyano, hydroxyl, nitro, acyl, Ci-30 alkyl and Ci- 3o alkoxy group; and X and Y are independently methyl or a represented by one of the following chemical formula 2-1 to 2-14, and at least one of X and Y is represented by one of the following chemical formula 2-1 to 2-14. (wherein (*) represents a bond, bl ring is optionally substituted by one or more substituent selected from the group consisting of halogen atom, amide, cyano, hydroxyl, nitro, acyl, C1-30 alkyl and Ci-30 alkoxy group; A is independently S or O; and, R, Ri, R2 and R3 are independently hydrogen, Cj-I5 alkyl, Ci-I5 alkoxy, C6-20 aryl or C6-20 heteroaryl; and, n is an integer of from 1 to 10).
