Abstract
Improving thephotovoltaicperformanceofCdSequantumdotssensitizedsolarcells (QDSSCs)using0.2wt%ofsinglewalledcarbonnanotubes/Titania(SWCNTs/TiO2) nano- compositephotoanodeisreported.TheseSWCNTs/TiO2 nanocompositefilmswere prepared bymechanicalmixingandspreadonthephotoanodebyadoctorblademethod. The currentdensity–voltage(J–V) characteristiccurvesofsuchassembledQDSSCswere measuredatAM1.5simulatedsunlight.SolarcellsbasedonSWCNTs/TiO2 nanocomposite photoanode achieves58%increaseinpowerconversionefficiency(η) comparedwith those basedonplainTiO2 NPs photoanodeunderaAM1.5simulatedsunlightandfor dippingtimeof6h.Thesignificantimprovementof Jsc and η for CdSeQDSSCsbasedon SWCNTs/TiO2 nanocompositephotoanodeisduetotheenhancementintheabsorptionof the incidentlightandrapidelectrontransportthroughtheSWCNTscomparedtotheplain TiO2 NPs. Furthermore,thelinearincreasein Jsc with increasingintensityofthesunlight indicatesthesensitivityoftheassembledcells
