The aim of this research was to investigate the influence of three key factors on photovoltaic (PV) cell performance: the concentration of CuO nanoparticles in TiO2-CuO nanocomposites, the loading concentration of N3 dye, and the loading time of N3 dye. These factors were found to significantly affect PV cell performance. The study utilized an ex-situ approach to prepare the necessary nanocomposites, which were then characterized using various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-VIS) spectroscopy, and photoluminescence (PL) spectroscopy. PV cell performance was evaluated through analysis of its current-voltage characteristics and assessment of parameters including short circuit current, open circuit voltage, fill factor, and power conversion efficiency. Optimization revealed that a dye-sensitized solar cell (DSSC) comprising a 20 wt.% CuO loaded TiO2 nanocomposite, with a 3% N3 dye loading concentration and a 2-hour dye loading time, exhibited the highest power conversion efficiency, reaching 5.273%.
