BipyridylrutheniumdyeN3andN719wassynthesized,purifiedbythegelchromatogrammethodandcharacterizedbytheprotonNMRandUV-Visspectra.Afterthepurificationmostoftheimpuritiesthatdecreasedthephotoelectrochemicalpropertieswereremovedandtheopen-circuitvoltage(V_(oc)),short-circuitphotocurrentdensity(J_(sc))andoverallphoto-electricconversionefficiency(η)ofthedye-sensitizedsolarcells(DSCs)increaseddramatically.Thestandardcurveofabsorbancevs.concentrationofN3andN719dyewasachievedbyusingUV-Visquantitativeanalyticspectrophotometry.ThismethodwasemployedtodeterminetheconcentrationofthedyesolutionaftercoatingofTiO_2films.Thelinearconcentrationrangeofabsorbancevs.concentrationofN719wasbetween6.25×10~(-6)mol·L~(-1)and1×10~(-4)mol·L~(-1)withthemolarextinctioncoefficient(ε)1.58×10~4L·mol~(-1)cm~(-1)atawavelengthof533～531nmand1.50×10~4L·mol~(-1)·cm~(-1)atawavelengthof393～384nm,accordingly.ThelinearconcentrationrangeoftheN3dyewas6.25×10~(-6)mol·L~(-1)to1.5×10~(-4)mol·L~(-1)withεof1.47×10~4L·mol~(-1)·cm~(-1)atawavelengthof538～535nmand1.48×10~4L·mol~(-1)·cm~(-1)atawavelengthof399～393nm.
