Abstract

The invention provides a device for obtaining an improved efficiency in a photo-voltaic, nano-structured, dye sensitized cell structure, comprising a photo-active working electrode (WE1), a counter electrode (WE2) and an electrolyte (5) arranged therebetween. The cell structure thereby forms a tandem cell in that the counter electrode also is a photo-active electrode, whereby the photo-active working electrode and/or the photo-active electrode are built on a transparent substrate. Furthermore, both the photo-active working electrode and the photo-active electrode are made of porous nano-structured film and the photo-active working electrode is dye sensitized with a first dye (Dye1). The first dye is selected such that the electron injection into the working electrode is so fast that the red-form of a redox-couple in the electrolyte as fast as possible replaces an injected electron. The second dye (Dye2) is selected such that it has a long lived excited state. In this case the material in the counter electrode is comprised of a semi-conductor having a large band-gap. In an alternative embodiment, the working electrode is dye sensitized corresponding to the first embodiment, whereas the counter electrode is comprised of a semi-conductor with a band-gap having absorption in the visible and/or infra red region, whereby the light absorption in this electrode is further enhanced by a dye having been adsorbed onto the surface of said electrode.
