An organic dye used in a dye-sensitized solar cell is described, having general formula (1): D-Sp1-Ch-Sp2-Acc-Y  (1) wherein the groups D, Ch, Acc and Y are conjugate with each other, the group D is a donor group, the group Ch is a chromophore rendering low HOMO-LUMO gap or a polyaromatic chromophore, the group Acc is an acceptor group, the group Y is an anchoring group, and each of Sp1 and Sp2 represents a single bond or a spacer group allowing conjugation between the groups D and Ch or between the groups Ch and Acc. |
