Definitions
- the invention relates to electrodes which comprise spherical allotropes, in particular silicon and / or carbon nanotubes, and their use in organic semiconductor technology.
- Electrodes for optoelectronic components based on organic conductors such as PANI, PED0T: PSS (polystyrene sulfonic acid) etc.
- the conductivity, the transparency for light, the electronic work function and / or the surface properties of these electrodes can still be optimized.
- the object of the present invention is therefore to provide a new electrode with improved (opto) electronic properties for organic semiconductor components and optoelectronic components.
- the invention relates to an electrode for optoelectronic and / or organic semiconductor components, which comprises allotropes.
- the invention also combines, for example, allotropes with organic conductors or semiconductors (typically conjugated polymers) to form a semi-transparent or non-transparent electrode.
- the electrodes can comprise the allotropes either in their metallic conductive form or in their semiconducting form.
- metallic-conductive allotropes are, for example, from the literature (ZF Ren, ZP Huang, J.. Xu, DZ Wang, JH Wang, L. Calvet, J. Chen, JF Klemic, and MA Reed, "Large Arrays of Well-Aligned Carbon Nanotubes ", Proceedings of 13th International Winter School on Electronic Properties of Nove Materials, Pages 263-267, (1999).
- Nanotubes have a variety of unique electronic, optical and mechanical properties.
- Single-walled nanotubes have high tensile strength and, depending on the diameter and chirality, can be metallic, semiconducting or insulating.
- chemical derivatization of nanotubes can also make sense, because this can influence their solubility and processability.
- the derivatized and / or soluble nanotubes can be used as part of a phase mixture in organic functional polymers of microelectronics.
- Spherical allotropes such as nanotubes are e.g. in Nature 1991, vol. 354, pages 56 to 58. There are silicon and carbon nanotubes.
- the alltotropes can either be added to conductive organic materials and / or drawn on substrates.
- the electrodes can either be realized purely with metallic allotropes, or by means of composite materials with metallic allotropes and / or with semiconducting allotropes.
- the following allotropes are suitable for positive / negative electrodes, which are formed by prior deposition of a suitable catalyst on substrates such as glass, metal (molybdenum), semiconductors (silicon) or also on foils (PET).
- a combination of at least two elements selected from the group of conductive substrates (conductive oxides (ITO), doped semiconductors (silicon, germanium ...), - of metals such as AL, Ag ... is also suitable for positive / negative electrodes. . or
- non-conductive substrates glass, foils, ...) on which allotropes are applied either in their purest form or in mixtures with conductive or non-conductive binding materials (polymers ).
- organic material or “functional polymer” or “polymer” here encompasses all types of organic, organometallic and / or organo-inorganic plastics (hybrids), in particular those which are described in English e.g. be called “plastics”. These are all types of substances with the exception of the semiconductors that form the classic diodes (germanium, silicon) and the typical metallic conductors. A restriction in the dogmatic sense to organic material as carbon-containing material is therefore not provided, but rather is also due to the widespread use of e.g. Silicones thought.
- polymer in the functional polymer is historical and therefore contains no information about the presence of an actually polymeric compound.
- functional polymer can refer to semiconducting, conducting and / or insulating substances.
- Metallic allotropes or nanotubes grown (formed) on a substrate result in conductive electrodes with a a three-dimensional structure, for example a two-dimensional array with nanotubes on it, which has a large surface area.
- the increase in surface area that is to say the ratio of the substrate surface on which the allotorop is applied, to the usable electrode surface, that is to say the active area, can be increased further by the density of the planting, that is to say the grown allotropes and / or by their length ,
- Composite material for electrodes can e.g. can be produced by embedding metallic allotropes in a matrix of conductive functional polymer. In this mixture of the allotrope with the organic functional polymer, the conductivity and / or the transparency of the electrode can be optimized via the amount of allotrope, its concentration in the matrix. From this composite material e.g. an electrode can be printed as a solution.
- semiconducting allotopes can also be used as the positive electrode (electron acceptor) for heterojunction applications. It has recently been shown that nanotube composites with conjugated polymers show a strong photo effect (SB Lee, T. Karayama, H. Kajii, H. Araki and K. Yoshino, Synth. Met 121 (2001) 1591-1592 ).
- the optical properties of the electrode can be adjusted by changing the length of the allotropes.
- Allotropic or nanotubes of suitable length function like a ⁇ / 4 antenna that is used to absorb electromagnetic radiation.
- allotropes for example, allotropes with a length of 100 to 200 nm are used. The invention is explained in more detail below with the aid of examples:
- Example 1 is the embodiment of the invention as an organic solar cell or organic photodetector, based on a metallic nanotube electrode.
- the nanotubes are either deposited on a conductive substrate, as an alternative, the nanotubes can also be “grown” on a non-conductive substrate, that is, “formed by growing”.
- the nanotube electrode is coated with a conductive (optionally or optionally semitransparent polymer) (eg by means of a printing process from the solution).
- This electrode then comprises these layers - substrate optionally conductive layer, eg. B. Au, ITO, AI ... - nanotube (selectable adjustable length, arrangement) optionally conductive polymer.
- the organic semiconductor (or a mixture of organic p-type and n-type semiconductor) is then deposited on this electrode (for example by a printing process from the solution).
- the component is finished by applying a counter electrode (typically by thermal vapor deposition of a thin metal layer).
- the optical absorption can be increased by a suitable choice of the length of the nanotubes and their arrangement.
- the second example describes an organic solar cell or an organic photodetector based on a semiconducting nanotube electrode.
- the nanotubes are either deposited on a conductive substrate, alternatively the nanotubes can also be grown on a non-conductive substrate.
- the nanotube electrode is coated with a conductive (optionally semi-transparent polymer) (e.g. by printing from the solution).
- a conductive optionally semi-transparent polymer
- the organic semiconductor preferably a p-type semiconductor
- is deposited typically by solution printing process.
- the semiconducting nanotubes of the electrode act as n-type semiconductors, so that a photo effect occurs between the polymeric semiconductor and the nanotubes.
- the component is finished by applying a counter electrode (typically by thermal evaporation of thin metal layers).
- the optical absorption can be increased by a suitable choice of the nanotube length and the arrangement of the nanotubes.
- the third example describes an organic light-emitting diode (or an organic display) based on a nanotube electrode (nanotube electrode array).
- the nanotubes are either deposited on a conductive substrate, as an alternative, the nanotubes can also be grown on a non-conductive substrate, for contacting, the nanotube electrode is coated with a conductive (optionally semitransparent polymer) (e.g. by printing process from the solution).
- the organic semiconductor preferably a p-type semiconductor
- is deposited onto this electrode isting of substrate / (optionally conductive layer, for example Au, ITO, AI ...) / nanotube / (optionally conductive polymer) (typically through printing process from solution).
- the component is completed by applying a counter electrode (typically by thermal evaporation of thin metal layers).
- the semiconductor component is composed as follows: Step 1: Production of the underside: substrate / electrode 1 (metal) / organic semiconductor Step 2: pressing a grown nanotube electrode into the organic semiconductor. By pressing, the carbon nanotubes penetrate into the organic semiconductor and make contact. With this technology, either the electrode 1 or the nanotube electrode can be designed to be semi-transparent.
- the invention relates to electrodes which comprise spherical allotropes, in particular silicon and / or carbon nanotubes, and their use in organic semiconductor technology.
- the electrodes can either comprise only allotropes and / or allotropes which are embedded in an organic functional polymer.
