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.
描述了用于染料敏化太阳能电池中的有机染料,其具有一般式(1):D-Sp1-Ch-Sp2-Acc-Y(1),其中D、Ch、Acc和Y是相互共轭的基团,基团D是给体基团,基团Ch是使HOMO-LUMO间隙较低的色团或多芳香色团,基团Acc是受体基团,基团Y是锚定基团,Sp1和Sp2分别表示单键或允许基团D和Ch之间或基团Ch和Acc之间的共轭的空间基团。
