摘要

Eight heptamethine cyanine dyes were synthesized and investigated for application in dye sensitized solar cell. The photophysical properties of the dyes revealed differences in optical properties with respect to their structure. The performance of the cyanine dye-sensitized solar cells conformed to the photophysical properties of the cyanine dyes.
