An ink that can form a P-type layer in an organic electronic device. The ink includes at least nanoparticles of P-type semiconductor metal oxide(s) selected from among VO, NiO, MoO, WOand mixtures thereof and an ionomer, the ionomer being a perfluorosulfonate copolymer, the mass ratio between the ionomer and the nanoparticles of P-type semiconductor metal oxide(s) selected from among VO, NiO, MoO, WOand mixtures thereof being between 0.005 and 0.115. Also, a P layer of an organic electronic device, an electronic device and the formation method thereof.

Ink for forming P layers in organic electronic devices

An optoelectronic device having a layer comprising: poly(3,4-ethylenedioxythiophene); polystyrene sulfonate; and a compound (A) having formula: wherein 0&#x3c;x/y&#x3c;1, Ar1 and Ar2 represent aromatic rings, which may be identical or different, and at least one Ar1 and Ar2 comprises at least one hydrophobic substituent on its ring.

Forming of optoelectronic devices, particularly of inverted-type OPV cells

An organic electronic device having an architecture with an inverted structure, containing a substrate, a first electrode deposited on the substrate, a second electrode and at least one assembly including a multilayer stack disposed between the electrodes, the multilayer stack including the following, successively from the first electrode: an N-type layer; an electrically active layer; and a P-type layer comprising a mixture of poly(3,4-ethylenedioxythiophene):poly (styrene-sulfonate), the stack containing an additional layer, known as the adhesion layer, formed by at least one metallic oxide and inserted between, and in contact with, the active layer and the P-layer. Also, a method for producing such a device.

Organic electronic devices

This forming involves a composition including: poly(3,4-ethylenedioxythiophene) or PEDOT; polystyrene sulfonate or PSS; a compound (A) having formula: with 0&#x3c;x/y&#x3c;1; Ar1 and Ar2 representing two aromatic rings, which may be identical or different; Ar1 and/or Ar2 comprising at least one hydrophobic substituent on its ring.
