Summary: We enhance the photovoltaic performance of dye-sensitized solar cells (DSSCs) by introducing graphene quantum dots (GQDs). GQD emits green fluorescence (around 530 nm) in the ultraviolet wavelength range (around 340 nm), which is utilized to improve the light absorption ability of N719 dye. Co-sensitization of N719 dye with GQDs as auxiliary sensitizers enhances the photovoltaic performance of DSSCs. By measuring incident photon-to-current conversion efficiency (IPCE), we observe the photoresponse characteristics of DSSCs with different sensitization effects. The DSSCs with GQD+N719 co-sensitized photoanode show a 20% increase in photoelectric conversion efficiency, reaching 5.14%.

Summary: Hollow microsphere structure nickel sulfide (NiS) particles were prepared using a hydrothermal method. NiS/titanium dioxide nanofibers (NiS/TiO2 NFs) were prepared by adding NiS into TiO2 nanofibers through electrospinning. Dye-sensitized solar cells (DSSCs) with NiS/TiO2 NFs photoanode showed a photovoltaic conversion efficiency (PCE) of 5.63%, which is 40.75% higher than that of DSSCs without modification. The increased specific surface area of the hollow microsphere structure of NiS and the higher porosity provided by NiS/TiO2 NFs contributed to enhanced dye adsorption and reduced transmission resistance in the DSSCs, leading to the improved performance.
