Cathodic electrodeposition from aqueous solution of dense or open-structured zinc oxide films

Direct electrodeposition of zinc oxide films is reported for the first time. That this method of preparation is suited to large‐scale production could be important for applications of ZnO, e.g., in solar cells. In addition to a description of the preparation and properties of the films, it is shown that the morphology of the layer can be controlled, varying from compact to open (see figure) structures.
