NOVELTY - The organic solar cell comprises simple-, tandem- or multiple cells, where the organic cell is arranged onto flexible carrier materials, which are arrangeable onto curved or flexible carrier surfaces. The tandem- or multiple cell consists of a combination of p-i-n, n-i-p, n-i, i-p, p-n-i-p, p-n-i, p-i-p, n-i-p-n, n-i-n, i-p-n, p-n-i-p-n, p-n-i-n or p-i-p-n structures, in which several independent combinations are stacked over each other, where the independent combinations contain i-layer. The flexible carrier materials are films or textiles, and have adhesion agent.    USE - Organic solar cell useful in navigation and shipping, in cargo containers, in magnetic levitation trains, in aircraft wings, as a composite material, as a part of airport pavement, in aerospace, in transportation systems, as a part of a road surface, as a part of sports field and playgrounds, in outdoor advertising, in street furniture and park furniture, as a part of buildings or parts of buildings, as a part of garages, in car parks, in covered parking spaces, in retractable garage, in garden shed, in sheds, in greenhouses, as a part of vehicles, as a part of refrigeration units of vehicles in combination with cooling means, in air conditioners, in freezers and refrigerators, as a part of windmills or wind turbines, in dam walls, in water power plants, in dams, in masonry dams, in cooling towers, in outdoor areas of power plants, in chimneys, in solar islands, as a part of tents, in wind protection, for the operation of auxiliary engines, as a part of sports equipment, as a part of garments, as a part of life jackets, survival suits, survival island, in the garden area, as a part of tools, as a part of interior furnishings, in agriculture, as a part of small electric appliances, as a part of collars for animals, as a part of mobile milking devices, as a part of mobile electronic devices fixed to animals, as a part of photo paper, paper, cardboard and plastic, for the operation of desalination plants and drinking water treatment plants, as bank protection, as a part of jewelry, in combination with radio frequency identification chips, for operating medical measuring instruments, pacemakers, painkiller pumps, as a part of textiles, in the field of logistics, for operating identifying and labeling of containers in combination with radio frequency identification chips, in railway wagons and freight of all types, as a part of contact lenses in combination, in combination with electronic security features of bank notes and documents of any kind, in water-repellent textile, in curved surfaces, in adhesive films, in connection with energy buffer and energy storage media, in combination with thin-film batteries, for corrosion protection, and in connection with organic light-emitting diodes, and with fastening systems (claimed).    ADVANTAGE - The organic solar cell can be economically produced with reduced energy consumption.    DETAILED DESCRIPTION - The organic solar cell comprises simple-, tandem- or multiple cells, where the organic cell is arranged onto flexible carrier materials, which are arrangeable onto curved or flexible carrier surfaces. The tandem- or multiple cell consists of a combination of p-i-n, n-i-p, n-i, i-p, p-n-i-p, p-n-i, p-i-p, n-i-p-n, n-i-n, i-p-n, p-n-i-p-n, p-n-i-n or p-i-p-n structures, in which several independent combinations are stacked over each other, where the independent combinations contain i-layer. The flexible carrier materials are films or textiles, and have adhesion agent on a side opposite to an organic layer system. The organic solar cells are self-adhesively implemented with the adhesion agent that is an adhesive and a Velcro fastener component.
