Abstract—Nanostructured thin films of pure Cu2O, Fe2O3
and bilayered α-Fe2O3/Cu2O were deposited on ITO glass
substrates using simple Spray pyrolysis method. All samples
were characterized using XRD, AFM and UV–Vis
spectrometry. Photo electrochemical properties were also
investigated in a three-electrode cell system. UV-Vis absorption
spectrum for pure Cu2O, Fe2O3 and bilayered Fe2O3/Cu2O
shows absorption in visible region. All nanostructured thin film
samples were used as photoelectrode in the
Photoelectrochemical cell for water splitting reaction. Our
results exhibit that the photocurrent of the Fe2O3/ Cu2O film
0.32 mAcm-2 was significantly higher than that of pure Fe2O3
(0.028 mAcm-2) under visible light illumination at 0.8 V/SCE.
