Novel Method For Manufacturing Organic Electronic Devices

摘要

The present invention relates to a method for manufacturing organic electronic devices including a dipyrannylidene film as an anodic interface layer, the method being carried out in a vacuum and without any exposure to air. The invention also relates to organic devices resulting from the method, more specifically to organic solar cells (OSC).

主权项

1. 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, it being possible for said aryl or heteroaryl rings optionally to be 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.
