Abstract
Provided is a hole-blocking layer which has excellent basic characteristics such as high photoelectric conversion efficiency, while exhibiting excellent productivity. The hole-blocking layer is produced by a process that has a step of bringing an aqueous solution containing hydrogen peroxide and titanium (IV) oxysulfate into contact with the surface of a member on which the hole-blocking layer is to be formed, and holding the contact between the aqueous solution and the member at 50 to 120° C., so that an amorphous titanium oxide precursor precipitates on the surface of the member; and a step of drying the amorphous titanium oxide precursor that has precipitated on the member.
