Dye compound for dye-sensitized solar cells, dye-sensitized photoelectric converter and dye-sensitized solar cells
摘要
A dye compound for solar cells, a dye-sensitized photoelectric converter and dye-sensitized solar cells are provided. The photoelectric conversion efficiency of solar cells is improved by using the dye compound:
of which X is at least one aromatic group and symmetric about the X-R 1 bond axis or at least hetero aromatic group having at least one hetero atom chosen from N and S and symmetric about the X-R 1 bond axis; R 1 is substituted or unsubstituted C1 to C20 cyclic alkyl or substituted or unsubstituted C1 to C20 linear alkyl; L 1 and L 2 are substituted or unsubstituted hydrocarbons having 2 to 8 conjugated p-orbitals; Y 1 and Y 2 are better electron-withdrawing groups than X and may contain at least one acidic hydrogen which is able to form a hydrogen bond.
