Abstract
Disclosed is a method for manufacturing an organic optoelectronic device, the method including: coating a second layer composition on a mediator; and forming a second layer of thin film on a first layer by moving the second layer composition coated on the mediator onto the first layer, wherein the second layer composition contains a donor and an acceptor and the acceptor includes a non-fullerene compound.
Claims10
A method for manufacturing an organic optoelectronic device, the method comprising:
- coating a second layer composition on a mediator;
- and
- forming a second layer of thin film on a first layer by moving the second layer composition coated on the mediator onto the first layer,
- wherein the second layer composition contains a donor and an acceptor and the acceptor includes a non-fullerene compound,
- wherein when a bottom portion and a top portion are separated in the second layer of thin film formed on the first layer, the bottom portion being in contact with the first layer and the top portion being not in contact with the first layer, the acceptor is more abundant than the donor in the top portion and the donor is more abundant than the acceptor in the bottom portion.
A method for manufacturing an organic optoelectronic device, the method comprising:
- coating a second layer composition on a mediator;
- and forming a second layer of thin film on a first layer by moving the second layer composition coated on the mediator onto the first layer, wherein the second layer composition contains a donor and an acceptor and the acceptor includes a non-fullerene compound,
- further comprising, before the coating of the second layer composition on the mediator, preparing a mediator containing a polyurethane acrylate oligomer,
- wherein in the preparation of the mediator, a chemical agent containing a hydroxy, carboxy, or fluoro group is further added to the mediator such that w<−1 is satisfied when the interfacial energy difference between the mediator and the second layer is denoted as A, the interfacial energy difference between the second layer and the first layer is denoted as B, the interfacial energy difference between the mediator and the first layer is denoted as C, and a value of (A−B)/C is denoted as w.
