Origin of Photoresponse Transition of Copper Electrode from p-Type to n-Type
Abstract:
Electrochemical and photoelectrochemical behavior for copper electrode in borax buffer solutions in the absence or in the presence of chloride ions were studied by potentiodynamic scan and photocurrent action spectrum. The photoresponse for Cu electrode in the absence of chloride ions shows p-type and the photoresponse transition from p-type to n-type in the presence of chloride ions is attributed to Cu2O film doped by Cl-ions, not to the formation of CuCl.
