Method for manufacturing organic electronic devices

A process for the manufacture of an organic electronic device, comprising at least the following stages:

• (i) the deposition by vacuum evaporation, on a substrate, of a film comprising at least one compound of following formula (I):
• in which:
• Xa and Xb, which are identical or different, are chosen from N, P, O, S, Se or Te atoms,
• R1, R2, R3 and R4, which are identical or different, represent a group chosen from aryl or heteroaryl rings having from 4 to 10 carbon atoms, said aryl or heteroaryl rings being optionally substituted by one or more halogen atoms or —OH, —CN, —NO2 groups, alkyl having from 1 to 30 carbon atoms, alkoxy —OCnH2n+1 or ester —C(O)OCnH2n+1 groups, in which 0≦n≦16,
• (ii) the deposition under an inert atmosphere of a photosensitive active layer,
• (iii) optionally, the annealing under an inert atmosphere of the photosensitive active layer deposited during stage (ii),
• (iv) the deposition under an inert atmosphere of an active layer for the dissociation of the excitons,
• (v) the deposition under an inert atmosphere of a layer acting as cathode electrode,
• said process being carried out with the exclusion of air, and wherein the organic electronic device has a power conversion efficiency greater than or equal to 3%.
