Özet
A one-step hydrothermal synthesis approach was used to produce nanostructured ZnO, SnO, and ZnO-SnO heterojunction photoanodes on fluorine-doped tin oxide (FTO) substrates. Four distinct photoanode configurations ZnO (S1), ZnO-SnO heteronanostructures (HNSs) (S2 and S3), and SnO (S4) were designed to thoroughly investigate the effect of compositional and structural alterations on film form, crystallinity, and optoelectronic capabilities. The thin films were studied using scanning electron microscopy (SEM) for surface morphology, Xray diffraction (XRD) for phase identification, Raman spectroscopy for vibrational analysis, UV-Vis spectroscopy for optical band gap estimation, and Fourier-transform infrared spectroscopy (FTIR) to identify the chemical bonding and metal-oxygen vibrations. The FTIR spectra revealed Zn-O stretching vibrations and Sn-O vibrations, confirming the formation of the ZnO-SnO HNSs. The photoanodes were sensitized using anthocyanin dye derived from pomegranate juice, a more sustainable alternative to synthetic dyes, and then converted into dyesensitized solar cells (DSSCs) using the AN50 electrolyte. The S2-based cell had the highest short-circuit current density (Jsc) and lowest charge transfer resistance (Rct), resulting in a conversion efficiency (eta) of 0.592 %. These findings highlight ZnO-SnO HNS' exceptional performance and potential as environmentally friendly photoanode materials for next-generation DSSCs.
