Abstract: Cuprous oxide (Cu 2 O) thin films are synthesised on Cu and tin oxide coated substrates by electrochemical pulse plating technique. The effect of current density and duty cycle on the growth of Cu 2 O films is studied. Structural studies reveal an optimum duty cycle of 33% to deposit well-crystallized Cu 2 O film. The effect of deposition parameters on the structural and optical properties are carried out. It is observed that annealing below 350 °C improved the crystallinity and grain size of Cu 2 O films whereas annealing above 450 °C exhibited the conversion of Cu 2 O into CuO. Photoelectrochemical solar cell studies showed improved performance for Cu 2 O electrodes and the results are discussed.
