Cells grown on rough fotosensu00ecveis orgu00e1nicas electrode with controlled morphology at the nanoscale, a device and a method for manufacturing the optoeletru00f3nico optoeletru00f3nico device include a first electrode disposed on a substrate.An exposed surface of the first electrode having a quadratic surface roughness average of at least 30 nm and a variation of the height of at least 200 nm, and the first transparent electrode.A layer of a first material conformal organic semiconductor is deposited on the first electrode for placement in the vapor phase organic, the first semiconductor material as a material of small molecule. A layer of a second semiconductor material is deposited on the organic layer conformal.At least part of the second layer of organic semiconductor material is in direct contact with the layer conformal. A second electrode is deposited on the second layer of organic semiconductor material. The first organic semiconductor material is of the type or of the type electron donor for the second organic semiconductor material, which is of another type of material.
