Abstract
The present invention provides a vehicle antifouling element that comprises a layer comprising a p-type semiconductor and a thin film that comprises an n-type semiconductor that is laminated on the surface of the p-type semiconductor layer. The thin film comprises a photocatalytic activity and the film thickness thereof is equal to or more than 5 nm and less than 60 nm.
Claims15
A vehicle antifouling element, comprising:
- a substrate comprising one of a glass and a metal sheet;
- a p-type semiconductor layer comprising a p-type semiconductor and formed on the substrate;
- and
- a thin film comprising an n-type semiconductor and formed on the substrate and the p-type semiconductor layer, the thin film being laminated on a surface of the p-type semiconductor layer on an opposite side of the substrate,
- wherein the n-type semiconductor of the thin film comprises a photocatalyst material which has a photocatalytic activity and the film thickness of the thin film is equal to or more than 5 nm and equal to or less than 60 nm.
