Abstract
Thin films of Cu2O were electrodeposited and characterised by techniques including XRD, SEM–EPMA, and spectrophotometry. The structure, morphology, composition, and optical properties of the films depend on the electrochemical bath and deposition parameters. The kind of substrate pretreatment process also seems to have an effect on film properties. The electrodeposited Cu2O films may be used for photovoltaic, photothermal, and oxygen sensor applications.
