Abstract
Organic or hybrid electronic device, having an NIP structure, such as an organic light-emitting diode, an organic photodetector, or an organic photovoltaic cell, comprising successively: a transparent substrate, a first transparent and electrically conducting electrode, an N type layer, an active layer comprising a polyethylenimine and: an electron donor material and an electron acceptor material, or a perovskite material, a P type layer, and a second electrode.
Claims17
Organic or hybrid electronic device, having an NIP structure, comprising successively:
- a transparent substrate,
- a first transparent and electrically conducting electrode,
- an N type layer,
- an active layer comprising a polyethylenimine and:
- an electron donor material and an electron acceptor material,
- or a perovskite material,
- a P type layer,
- a second electrode,
- wherein the active layer has a concentration gradient of polyethylenimine that increases in a direction towards an interface of the active layer and the N type layer.
Method for manufacturing an organic or hybrid electronic device, having an NIP structure, including at least the following successive steps:
- a) providing a transparent substrate coated, successively with a first transparent and electrically conducting electrode, and with an N type layer,
- b) forming an active layer by deposition of a solution containing a polyethylenimine, a non-chlorinated solvent, and, an electron donor material and an electron acceptor material, or a perovskite material, followed by annealing.
Organic or hybrid electronic device, having an NIP structure, comprising successively:
- a transparent substrate,
- a first transparent and electrically conducting electrode,
- an N type layer,
- an active layer comprising a polyethylenimine and:
- an electron donor material and an electron acceptor material,
- or a perovskite material,
- a P type layer,
- a second electrode,
- wherein the polyethylenimine in the active layer is intermixed with the electron donor material and an electron acceptor material, or the perovskite material;
- and wherein the electronic device is devoid of a separate polyethylenimine layer at an interface of the active layer and the N type layer.
