NOVELTY - The layered solar cell comprises an upper-side photovoltaic layer sequence that converts incident light into current, and a shaded underside facing away from the light. The photovoltaic layer sequence is connected to a functional layer sequence of the layered solar cell for improving the current yield. The functional layer sequence is formed on an underside of the photovoltaic layer sequence in the shaded region, and comprises a thermo-electric double layer, a structured Peltier layer sequence, a capacitively storing double layer, and chemically structured charge-storing layer.    USE - The layered solar cell is useful as a power source for mobile phones, portable computers, or power saving LED light sources, and in air conditioners, navigation systems, alarm systems, industrial roofing, industrial facades, buildings, outdoor canopies, shopping arcades, roof tiles, awnings, air-supported structures, vehicles including buses, trains, cars, trucks, camper van, vans, golf cars, boats, ships and yachts, deck areas, swimming pool-indoor surfaces, toys, clothing, tents, desert solar farms, roads, paths, tiles, billboards, parking over-roofings, self-sufficient household electricity networks, sewage treatment plants, household treatment plants, thermal sanitizer, consumer electronics, computer systems, garden equipments, lighting equipments, self-contained lighting systems and a solar panel.    ADVANTAGE - The efficient and compact layered solar cell exhibits high performance and power output, improved reliability and increased weather resistance.    DETAILED DESCRIPTION - The layered solar cell comprises an upper-side photovoltaic layer sequence that converts incident light into current, and a shaded underside facing away from the light. The photovoltaic layer sequence is connected to a functional layer sequence of the layered solar cell for improving the current yield. The functional layer sequence is formed on an underside of the photovoltaic layer sequence in the shaded region, and comprises a thermo-electric double layer, a structured Peltier layer sequence, a capacitively storing double layer, and chemically structured charge-storing layer. A sequence of inorganic layers has a closed porosity of 0.1-1 vol.%. The layer sequence comprises microstructured films with an individual layer thickness of 0.01-5 mu m. A layer of the cell layer is formed as a thermally compacted, inorganic, amorphous or polycrystalline layer. The thermally compacted layer of the cell layer is formed as a screen printed layer. The layers are applied on a flexible support in the form of a stably rolled composite having a diameter in centimeter. The cell layer is isolated from the microstructured films. The layers of sequence are electrically contacted in parallel. The inorganic layer is disposed adjacent to a transparent protection top-side and a lower-side support, and comprises metals, metal alloys and inorganic non-ionic semiconductor compounds. The composite is electrically connected via regulating microstructured conductive areas and provided with macroscopic port areas for the external power loss.
