Abstract
Thin film detector of ultraviolet radiation with high spectral selectivity option, and a structure placed between two electrodes, formed by the superposition of semiconductor thin films such as hydrogenated amorphous silicon and its alloys with carbon. The device is able to absorb a large quantity of UV radiation and to convert it into electric current being transparent to photons of longer wavelengths. Its deposition technique allows fabrication on substrates of glass, plastic, metal, ceramic types of materials (also opaque, also flexible), on which a conductor material film has been predeposited. It can be fabricated on substrates of any size.
