Abstract
A zinc oxide film is formed on an electroconductive substrate by electrodeposition. The electrodeposition is performed by immersing an electroconductive substrate and an electrode in an aqueous solution containing nitrate ion and zinc ion, and supplying a current passing through a gap between the electroconductive substrate and the electrode while vibrating the electroconductive substrate to stably form a uniform zinc oxide film free from anomalous growth of a crystal on the electroconductive substrate. The zinc oxide film is excellent in adhesive properties with the electroconductive substrate and suitable for a light-confining layer of a photo-electricity generating device.
