NOVELTY - The organic photoactive component such as solar cell or organic photodetector, comprises two electrodes and a layer, which is situated between the electrodes and which contains a layer comprising organic materials. The component contains a further layer consisting of organic and/or inorganic material. The layer designated as transparent covering layer/covering layer increases the efficiency of the photoactive component as a result of improved coupling-in light and/or reduced reflection and/or optimization of the optical field within the solar cell as a result of the formation of microcavity.    USE - Organic photoactive component for the production of solar cell or organic photodetector (claimed).    ADVANTAGE - The organic photoactive component can be manufactured with improved coupling-in light and/or reduced reflection and/or optimization of the optical field.    DETAILED DESCRIPTION - The organic photoactive component such as solar cell or organic photodetector, comprises two electrodes and a layer, which is situated between the electrodes and which contains a layer comprising organic materials. The component contains a further layer consisting of organic and/or inorganic material. The layer designated as transparent covering layer or covering layer increases the efficiency of the photoactive component as a result of improved coupling-in light and/or reduced reflection and/or optimization of the optical field within the solar cell as a result of the formation of a microcavity. The layer thickness of the transparent covering layer or covering layer is D, where D = d plus minus (0.2d), where d(n) = 201.9 -121.In + 20.In2 holds true and n is the optical refractive index of the covering layer. The photoactive component is a tandemsolarcell or triple solar cell, which consists of two electrodes and two layers lying between the electrodes that consist of a layer with organic material. The further layer serves as separate conversion contact of the recombination of the electrones and p-holes. The refractive index of the covering layer is 1.8 to 2.4 and the layer thickness of the covering layer is 10-150 nm. The photovoltaic component on the substrate consists of base contacts of metal, conductive polymers and/or a transparent conductive oxides. The optical microcavity is completely formed with a further optical microcavity in the arrangement of the organic layers. The photovolatic component consists of anti-diffusion layers of metals or transition metals, and thin layers of metals. The photovoltaic component consists of conversion contacts from thin metal layers, organic materials or inorganic materials and produced on a substrate from glass, aluminum foil, steel, textile materials or plastic foils. The photovoltaic component consists of materials, which conducts positive charge and is named as hole transport layer, and conducts negative charge that is named as electron transport layer. The photovoltaic component consists of materials that absorb photones as separate active layer and serves as exciton-block-layer and encapsulation. The photovoltaic component is produced by spin coating, dip-coating, drop casting, doctor-blading, chemical vapor phase deposition or organic vapor phase deposition, electro deposition or other chemical, electrochemical or wet chemical process or by screen printing, offset-printing, inkjet printing or other printing process or by magnetron sputtering process or cathode sputtering based process or through molecular beam epitaxy, roll-to-roll process, or by laminating film, self-assembled monolayers. The photovoltaic component is produced in reverse sequence.    DESCRIPTION OF DRAWING(S) - The figure shows an archetypal organic solar cell (Drawing includes non-English language text).
