Abstract
Pristine copper oxide (CuO) and manganese (Mn) doped CuO nanostructures with different ratios were synthesized via wet chemical method. As-prepared materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-rays (EDX), UV–Visible and emission spectroscopy. Further, the doped nanowires were employed in the hybrid solar cells in combination with P3HT and gave better current densities than their corresponding undoped counterparts. The photoactivity of synthesized materials was evaluated by the photocatalytic oxidation of Rhodamine B (RhB). The results showed that the 2% Mn doped CuO photocatalyst is highly photoactive than other corresponding undoped and doped CuO nanowires. The increase in solar cell efficiency and photocatalytic activity of the doped CuO nanowires is solely due to the improvement in the charge separation efficiency in the 2% Mn doped CuO nanowires.
