摘要：

The photoelectrochemical properties of copper oxide thin film (p-type) on the SnO2 : F coated glass (conducting glass) prepared by spray pyrolysis has been investigated as a function dopant and pH of electrolyte. X-ray diffractogram pattern of thin films confirm the cupric oxide (CuO) phase. Mn-doped samples exhibited decreased photoelectrochemical response as compared to undoped CuO. The onset of photocurrent in undoped CuO is at similar to120 mV, while in Mn doped CuO films it is similar to375 mV. The observed reverse effect of Mn-doping on the photoelectrochemical response of the films, can be attributed to the possible neutralization of naturally occurring majority charge carriers (holes) present in undoped copper oxide with the extra electrons furnished by the dopant Mn atoms, particularly, from their d orbitals. Better photoresponse has been observed at pH 13.
