Abstract
The present invention relates to a photovoltaically self-charging storage system having a layer structure in which a first material ( ), which forms a first redox system, a second material ( ), which forms a second redox system, and a photosensitive material ( ) are arranged in or between a first ( ) and a second electrically conductive layer ( ). At least one of the electrically conductive layers ( ) is transparent for visible light. The first and the second material ( ) are each in electrical contact with one of the electrically conductive layers ( ) and arranged in the layer structure in such a manner that, due to the effect of light, the photosensitive material ( ) induces a redox reaction A +B →A +B , which can be reversed if light ceases. The thickness of the layer over which the first ( ) and/or second material ( ) extends is configured in such a manner that a charge storage sufficient for operating an electrical consumer is made possible. The additional introduction of a catalyst material accelerating said back reaction enables the spatial separation of the direct reaction and the back reaction. The inventive system enables the photovoltaic conversion and charge storage using a simple layer structure in an advantageous manner.
