摘要： A device for back-scattering an incident light ray, including: a host substrate; a structured layer; a first face in contact with a front face of the host substrate; a second flat face parallel to the first face; a first material and a second material which form, in a mixed plane, alternating surfaces at least one of whose dimensions is between 300 nm and 800 nm, the mixed plane is between the first and second face of the structured layer; wherein the refractive index of the first and of the second material are different, the structured layer is covered by a specific layer, the specific layer is made of a material which is different from the first and second materials of the structured layer, and the specific layer is crystalline and semi-conductive.
