Abstract
This study primarily focuses on the efficiency of dye-sensitized solar cells (DSSCs), i.e., naturally sensitized solar cells, which were enhanced through the implementation of Zn2SnO4 compounds and zinc stannate (Zn2SnO4)/titanium dioxide (TiO2) nanofiber (NF) composites into the photoanode. The DSSCs’ photoanode properties of Zn2SnO4 compounds and Zn2SnO4/TiO2 NFs were also investigated using a variety of characterization techniques, including electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD), incident photon current efficiency (IPCE) measurement, and ${J}-{V}$ characterization, and. The findings demonstrate that adding Zn2SnO4 compound and Zn2SnO4/TiO2 NF composite to the photoanode enhances the DSSCs’ photovoltaic (PV) capabilities. The photoanode decorated with Zn2SnO4/TiO2 NFs displayed improved photoelectric conversion efficiency (PCE) ( $\eta $ ) in contrast to the reference TiO2 photoanode. The PV conversion efficiency ( $\eta $ ) has been reported to increase by around 51.07%. Based on these findings, the study demonstrates that Zn2SnO4/TiO2 NFs can be considered as candidate materials for boosting DSSCs’ PV efficiency.
