摘要：
Cuprous oxide (Cu2O) 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 Cu2O films is studied. Structural studies reveal an optimum duty cycle of 33% to deposit well-crystallized Cu2O film. The effect of deposition parameters on the structural and optical properties are carried out. It is observed that annealing below 350 degreesC improved the crystallinity and grain size Of Cu2O films whereas annealing above 450 degreesC exhibited the conversion Of Cu2O into CuO. Photoelectrochemical solar cell studies showed improved performance for Cu2O electrodes and the results are discussed. (C) 2003 Elsevier Science BX All rights reserved.
