Abstract
In this study, we used graphene oxide (GO) and magnetic beads (MBs) to modify the dye-sensitized solar cell (DSSC). The titanium dioxide (TiO2) colloid was mixed with GO and MBs which was deposited on the top of platinum-counter electrode. In addition, we measured the photovoltaic performances of dssc with different iodide concentrations of electrolyte. Furthermore, we investigated the photovoltaic performances of DSSC under different light intensities. The DSSC achieves a photovoltaic conversion efficiency of 6.78% under the light intensity of 30 mw/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> for the electrolyte of 0.0125 m iodide.
