In this work, we report some preliminary results concerning the fabrication of quaternary copper, indium, gallium, and selenium\ud CIGS nanowires that were grown inside the channels of an anodic alumina membrane by one-step potentiostatic deposition at\uddifferent applied potentials and room temperature. A tunable nanowire composition was achieved through a manipulation of the\udapplied potential and electrolyte composition. X-ray diffraction analysis showed that nanowires, whose chemical composition was\uddetermined by energy-dispersive spectroscopy analysis, were amorphous. A composition of Cu0.203In0.153Ga0.131Se0.513, very close\udto the stoichiometric value, was obtained. These nanostructures were also characterized by photoelectrochemical measurements:\udThey showed a cathodic photocurrent and an optical gap of 1.55 eV
