The Application of Dye-Sensitized Solar Cell Using rGO and MBs in Series-Parallel Under Low Illumination

The advantage of the dye-sensitized solar cell (DSSC) is utilized indoor fluorescent light illumination, but the output power of DSSC is not high enough. In this study, we provided a structure for DSSCs, and characterized the photovoltaic performances under air mass 1.5 global and indoor fluorescent light illumination. The photoanode of DSSC is based on titanium dioxide (TiO2) - magnet beads (MBs) - reduced graphene oxide (rGO) composited photoanode (TMGP), which was fabricated by hydrothermal method, spin coating, and doctor blade. According to the experimental results, adding MBs and rGO to DSSCs can enhance the charge transfer ability, reducing the occurrence of charge recombination, thereby improving the photovoltaic performance. DSSCs with TMGP photoanode can maintain a photovoltaic conversion efficiency of around 14 % under indoor light.
