Method of forming an optical device

The present invention, Providing a substrate including a first electrode to inject or receive charge carriers of a first type; By cross-linkable vinyl or ethynyl: depositing a first semiconductor material of the evaporation group in a solvent not soluble, to form an at least partially insoluble in the first layer on the first electrode in a solvent; By depositing a second semiconducting material from a solution in a solvent, the method comprising contacting the first layer to form a second layer comprising a second semiconductor material; And A second electrode to inject or receive charge carriers of the second type comprises the step of forming the second layer, The first layer is heated after the deposition of the first semiconductor material, a method of producing an optical device, at least in part by one or more of a water-insoluble vacuum and ambient drying treatment.
