  • Patent number: 11283304
    Abstract: A rectenna device (400) for converting incident light to electrical energy is disclosed. The rectenna device comprises a substrate (402), a first metallic layer (404) having a predefined thickness deposited on top of the substrate, a rectifying element (405) deposited on top of the first metallic layer, a second metallic layer (408) deposited on top of said rectifying element and configured to collect electromagnetic waves of the incident light and to couple it into plasmonic waves within the rectenna device, the second metallic layer comprising an array of a plurality of metallic patches (410) spaced from each other according to a predefined spacing, each metallic patch having predefined dimensions.
    Type: Grant
    Filed: November 28, 2018
    Date of Patent: March 22, 2022
    Assignees: UNIVERSITE D'AIX-MARSEILLE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE CENTRALE DE MARSEILLE, UNIVERSITE DE TOULON

  • Patent number: 11277095
    Abstract: A method for producing a multicoloured optoelectronic device is provided as well as a device produced with that method. An electrically conducting substrate including a first and second portion adjacent to the first portion is obtained. Then a first photoactive material having optical properties in a first frequency range is deposited on the first portion and a second photoactive material differing from the first photoactive material having optical properties in a second frequency range is deposited on the second portion, the first photoactive material contacting the second photoactive material, forming a photoactive layer of the multicoloured optoelectronic device.
