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.展开更多
