Abstract
A method for the production of organic solar cells or photodetectors, particularly based on organic polymers, comprising the following steps:—a first organic n- or p-conductive semiconductor layer is applied to an electrode, to the solid first organic semiconductor layer is applied a second organic semiconductor layer of the respective other conductivity whose solvent partially dissolves the first organic semiconductor layer, such that the first semiconductor layer mixes with the second mixed layer;—a second electrode is applied opposite the first.
Claims11
A method for the production of organic solar cells or photodetectors, the method comprising:
- applying a first organic n- or p-conductive semiconductor layer to a first electrode, the first organic semiconductor layer having a first conductivity,
- applying a second organic semiconductor layer to the first organic semiconductor layer, the second organic semiconductor layer having a second conductivity opposite to the first conductivity, the second organic semiconductor being present in a solvent when applied to the first organic semiconductor layer, the solvent being capable of partially dissolving the first organic semiconductor layer, such that a portion of the first semiconductor mixes with a portion of the second semiconductor to form a bulk heterojunction mixed layer, and
- after applying the second organic semiconductor layer to the first organic semiconductor layer, applying a second electrode opposite the first electrode.
A method for producing organic solar cells or photodetectors, the method comprising:
- applying a solution comprising a second organic semiconductor and a solvent on a first layer, the first layer comprising a first organic semiconductor that is at least partially soluble in the solvent;
- evaporating the solvent to form a second layer and a bulk heterojunction mixed layer between the first and second layers, the second layer comprising the second organic semiconductor and the bulk heterojunction mixed layer comprising a mixture of the first and second organic semiconductors;
- and
- disposing a second electrode on the second layer after evaporating the solvent.
