  • a thin-film energy system u contains at least one energy store such as a rechargeable battery and / or a battery and / or a capacitor in a thin-film construction, that is to say built on a thin substrate with a construction height of the entire energy store in the millimeter range.
  • the associated energy storage devices that is to say rechargeable batteries and / or batteries and / or capacitors, must have a high degree of mechanical flexibility so that they can be used in functional SmartCards such as bank cards or telephone cards with additional functions.
  • An example of such a thin-film energy storage device is a lithium / polymer electrolyte battery with a construction height of approximately 1 ⁇ m to 10 mm.
  • Thin-film energy systems are preferably flexible.
  • a disadvantage of the known systems is that they have a short lifespan in comparison to the devices driven by them and, on the one hand, are practically not rechargeable, because the electrical devices for recharging are space-consuming, complex and expensive and, on the other hand, are also mutually exclusive Does not offer to replace the systems directly because it is difficult to replace these smallest components.
  • the object of the present invention is therefore to provide rechargeable mobile thin-film energy systems.
  • the invention relates to a thin-film energy system with at least one rechargeable thin-film energy store and at least one thin-film energy converter, the energy converter being electrically conductively connected to the rechargeable energy store.
  • the energy converter comprises at least one photovoltaic cell.
  • the photovoltaic cell comprises at least one organic functional polymer.
  • a flexible photovoltaic cell is particularly preferred.
  • organic functional polymer is understood to mean any layer of a semiconductor component that is not made from the material of conventional silicon-based semiconductor technology. There is no restriction to the size of molecules, as the expression “..polymer” would suggest, rather so-called “small molecules” can also fall under this term.
  • the components with organic functional polymers are preferably applied to flexible substrates.
  • a “thin-film energy system” refers to a flexible energy system, for example, which has a height in the range between 1 ⁇ m and 10 mm, preferably between 10 ⁇ m and 1000 ⁇ m.
  • the energy converter is preferably an organic photovoltaic cell that can be produced using the thin-film process and has a height of between 1 ⁇ m and 8 mm. All accumulators / batteries / capacitors whose overall height does not significantly exceed the stated dimensions can be used as an energy store.
  • the photovoltaic cell is integrated directly into the energy store, so that, for example, an electrode is a common electrode and is used by the photovoltaic cell and the energy store.
  • the thin-film energy system is preferably mobile, that is to say it can be operated independently of a network connection.
  • Figure 1 shows an example in which the energy converter, e.g. the photovoltaic cell is placed on one of the storage electrodes.
