摘要：

With increasing demand for renewable energy sources, efforts have been made to develop dye-sensitized solar cells (DSSCs) that utilize renewable green materials with cost-effective fabrication procedures. In this paper, we report a green, low-cost carbon(Cx)/liginin/alpha-Fe2O3 (LFCx) composite photoanode (PA) with tunable electrochemical performance to improve efficiency of DSSC. The DSSC was assembled using an LFCx thin-film photoanode on an indium-doped tin oxide (ITO) glass, activated carbon counter-electrode. Characterization was conducted using scanning electron microscopy, UV-Vis spectroscopy, interferometry, and photovoltaic performance testing. The assembled DSSC exhibits a bandgap of 3.04 eV, with a short-circuit current density (Jsc) of 10.21 mA cm-2 and an overall efficiency of 3.46% at 1 sun illumination. The power conversion efficiency reported in this research is 47.5% greater than the highest reported value to date.
