  • Method for producing a multicolour optoelectronic device comprising multiple photoactive materials and optoelectronic device thus produced
    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.
