Abstract
In this work the influence of the dopants Ni and Ni+Co on the photoresponse of sprayed ZnO thin film electrodes in acetonitrile solution was studied. In the case of an Ni-doped ZnO electrode, the photocurrent spectrum showed the extension up to a wavelength of light of 580 nm, while the (Ni+Co)-doped electrode exhibited an extension up to around 700 nm. These extensions are attributed to the dopant energy bands lying in the bandgap region of ZnO.Keywords
