We report a peculiar banyan root like Mg-doped ZnO photoanode to result in high electron transport, retardation of interfacial charge recombination, improved light harvesting efficiency, and overall enhanced photovoltaic performance of dye-sensitized solar cells (DSSC). DSSC based on a 5 mol % Mg-doped ZnO electrode of very low thickness, ∼4 μm, gained an improved short-circuit current density of 9.98 mAcm-2, open-circuit photo voltage of 0.71 V, fill factor of 0.58, and overall conversion efficiency of 4.11% under 1 sun illumination.
