Abstract
A process for stably producing a zinc oxide thin film by electrolysis with excellent adhesion to a substrate is described. In particular, a zinc oxide thin film suitably used as a light confining layer of a photoelectric conversion element is formed on a conductive substrate by applying a current between a conductive substrate immersed in an aqueous solution containing at least nitrate ions, zinc ions, and a carbohydrate, and an electrode immersed in the solution.
