摘　　要：Organic dyes with ethoxy-substituted oligo-phenylenevinylene as chromophores were synthesized for dye-sensitized solar cells （DSSCs）, and the detailed relationships between the dye structures, photophysical properties, electrochemical properties, and performances of DSSCs were described. The dye S3O showed broad IPCE spectra in the spectral range of 350--750 nm, and the dye S1P showed solar energy-to-electricity conversion efficiency （1/） of up to 4.23% under AM 1.5 irradiation （100 mW/cm2） in comparison with the reference Ru-complex （N719 dye） with an r/value of 5.90% under similar experimental conditions.Organic dyes with ethoxy-substituted oligo-phenylenevinylene as chromophores were synthesized for dye-sensitized solar cells （DSSCs）, and the detailed relationships between the dye structures, photophysical properties, electrochemical properties, and performances of DSSCs were described.
