ABSTRACT 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/α‐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.
