(a) J–V characteristics of the bare ZnO-nanorod and ZnO/Au-nanocomposite DSSCs, measured at 1 sun, AM 1.5 G illumination, (b) short-circuit photocurrent density of the bare ZnO-nanorod and ZnO/Au-nanocomposite DSSCs measured at different incident wavelengths and (c) optical absorptions of dye N719 in 0.1 mM KOH aqueous solution for bare ZnO-nanorod and ZnO/Au-nanocomposite photoelectrodes. The optical absorption was measured by removing the dye molecules from the respective photoelectrodes (size = 1 cm2) by dipping them in a 0.1 mM KOH aqueous solution (2 mL) for 5 min.
