ABSTRACT:
A photosensitizer dye is provided. The photosensitizer dye contains a Ru complex represented by the following formula (1):wherein Y1and Y2independently represent hydrogen atom (H), lithium (Li), sodium (Na) or tetra-alkyl ammonium groups (as represented by the following general formula (2)).wherein A, B, C and D independently represents CmH2m+1(m=1˜6).Wherein X1represents one of the following formulas (3)˜(8) and X2represents H or a group the same as X1,
