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 V 2 O 5 , NiO, MoO 3 , WO 3 and 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 V 2 O 5 , NiO, MoO 3 , WO 3 and 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. |
