Abstract:

In order to enhance the dispersion property of Fe3O4 nanoparticles in Agarose-based magnetic polymer electrolytes for Dye-sensitized solar cell (DSSC), PEG200 was choosen to modify the magnetic polymer electrolytes. The electrochemical properties of polymer electrolytes with different content of PEG200 were studied by Electrochemical Impedance Spectroscopy (EIS). It was found that the electrolyte has an optimal conductivity of 2.88×10-3 Scm-1 when the mass fraction of PEG200 is 61.8wt% of Fe3O4 nanoparticles in the electrolyte. The electron lifetime of electron charges in photoanode increased and then decreased when the concentration of PEG200 increased. At the concentration of PEG200 of 68.3wt%, the cell reached the largest electron lifetime.
