An article including a nanostructured functional coating disposed on a substrate is described. The functional coating is characterized by both anti-reflection properties and down-converting properties. Related optoelectronic devices are also described.

主权项

1. An article, comprising:
a substrate; a multi-layer structure disposed on a surface of the substrate; and a nanostructured functional coating disposed on an electromagnetic radiation-receiving surface of the substrate, wherein the electromagnetic radiation-receiving surface is opposite to the surface on which the multi-layer structure is disposed, wherein the nanostructured functional coating is characterized by both anti-reflection properties and down-converting properties, wherein the nanostructured functional coating comprises an anti-reflection layer, wherein the anti-reflection layer comprises an array of nanostructures, wherein the nanostructured functional coating comprises a down-converting material present in the form of nanostructures selected from nanowires and nanorods extending substantially perpendicular to the surface of the substrate; wherein the article is a photovoltaic device.
