  • DYE COMPOUND FOR DYE-SENSITIZED SOLAR CELLS, DYE-SENSITIZED PHOTOELECTRIC CONVERTER AND DYE-SENSITIZED SOLAR CELLS
    Publication number: 20100132796
    Abstract: It relates to a dye compound for solar cells, a dye-sensitized photoelectric converter and dye-sensitized solar cells. The photoelectric conversion efficiency of solar cells is improved by using the dye compound for solar cells, expressed by formula 1: in which X is at least one aromatic group and symmetric about the X—R1 bond axis or at least hetero aromatic group having at least one hetero atom chosen from N and S and symmetric about the X—R1 bond axis; R1 is C1 to C20 cyclic substituted or unsubstituted alkyl or C1 to C20 linear substituted or unsubstituted alkyl; L1 and L2 are substituted or unsubstituted hydrocarbons having 2 to 8 conjugated p-orbitals; Y1 and Y2 are better electro-withdrawing group than X and may contain at least one acidic hydrogen which is able to have hydrogen bond.
