1. A ruthenium complex, which is represented by the following formula (I):RuL2(NCS)2Am(I)whereinL is 2,2'-bipyridyl-4,4'-dicarboxylic acid, 2,2'-bipyridyl-4,4'-disulfonic acid, or 2,2'-bipyridyl-4,4'-diphosphonic acid;A is a quaternary phosphonium cation; andm is 1, 2, 3, or 4. The ruthenium complex can be used in a Dye-Sensitized Solar Cell (DSSC). Hence, the photoelectric characteristics of the DSSC manufactured witn the ruthenium complex of the present invention can be improved. |
