Study On Synthesis Characterization And Electrical Property Of Cerium Tungstate In Dye-sensitized Solar Cell

It is important to the application of cerium tungstate as counter electrodes(CEs) catalysts in dye-sensitized solar cell(DSC), and they can improve the penetration each other. The transition metal mixed oxide catalysts were high productivity, low cost, et al, while they were not used in DSC. Building on the current on the cerium tungstate, this research designed and synthesized a series of CEs catalytic materials. It is purpose that shows the low cost and to improve its stability. Here, we introduce some cerium tungstate catalytic materials.Part one: the cerium tungstate was synthesized using the diffirent of six methods, X-ray diffraction(XRD) and Scanning electron microscopy(SEM) were used to characterize them.The electrochemical process was characterized by cyclic voltammetry(CV), electrochemical impedance spectroscopy(EIS) and Tafel-polarization experiments.Part two: the tungstate and cerium using the diffirent ratio were synthesized. XRD and SEM were used to characterize them. The thermal performance was characterized by DSC.The electrochemical process was characterized by J-V, CV, EIS and Tafel-polarization experiments.Part three: tungstate:cerium=1:0 and tungstate:cerium=17:3 catalysts imbedded in Carbon nanotubes and Charcoal Active Powder respectively were synthesized. XRD and SEM were used to characterize them. The electrochemical process was characterized by J-V, CV,EIS and Tafel-polarization experiments.Part four: W18O49 and WO3 catalysts imbedded in Carbon nanotubes and Charcoal Active Powder respectively were synthesized. XRD and SEM were used to characterize them. The electrochemical process was characterized by J-V, CV, EIS and Tafel-polarization experiments.
