Performance of Dye-sensitized Solar Cells Using Titanium Dioxide and Silver Nanowire Composite Film

In this study, various concentrations of silver nanowires (AgNWs) were added to titanium dioxide (TiO 2 ) paste, which was then uniformly coated onto indium tin oxide (ITO) conductive glass substrates by a doctor blade method.The coated substrate underwent a molding process to ensure an average film thickness of 10 m.Subsequently, the substrate was annealed in a hightemperature furnace to enhance the structural stability and electrical performance of dyesensitized solar cells (DSSCs).After annealing, DSSCs were assembled with a photoanode, a thermoplastic film, and a counter electrode by a sandwich stacking method.The short-circuit current density (J sc ) and photovoltaic conversion efficiency (PCE) of the assembled DSSCs with various concentrations of AgNWs were measured.The DSSC without AgNWs presented a J sc of 7.71 mA/cm 2 and a PCE of 3.54%.In contrast, the DSSC with 0.05 wt% AgNWs exhibited an increased J sc of 8.14 mA/cm 2 and a PCE of 4.14%, representing a significant efficiency improvement.
