DETAILED DESCRIPTION - The photovoltaic element for conversion of electromagnetic radiation to electrical energy, comprises a carrier partially transparent for electromagnetic radiation, a dye solar cell (126) with a first electrode, an n-semiconductive metal oxide, a dye (122), which absorbs electromagnetic radiation in a first spectral range, a solid p-semiconductor, and an organic solar cell (130) with an acceptor material (132) and a donor material (134). The acceptor material and/or the donor material comprise an organic material. The organic solar cell comprises a second electrode on a side opposite the dye solar cell and is designed to absorb electromagnetic radiation in a second spectral range, which is partially different from the first spectral range. The first electrode and/or the second electrode is partially transparent for the electromagnetic radiation. The photovoltaic element has a two-contact tandem-cell design. The photovoltaic element has first and second electric contact electrically connected with the first and second electrodes, and a charge recombination zone between the dye solar cell and organic acceptor material of the organic solar cell. The charge recombination zone has a layer thickness of greater than 0.5 nm. Between the charge recombination zone and the organic solar cell, an electron transport layer is subjected. The organic solar cell has a transition between the layer of the acceptor material and a layer of the donor material. The layer of the acceptor material is arranged on a side turned to the dye solar cell, and the layer of the donor material is arranged on a side turned to the dye solar cell. The transition has a mixing layer between the acceptor material and the donor material. Between the first electrode and the n-semiconductive metal oxide, a powder layer with a transparent powder metal oxide is subjected. The powder layer has a layer thickness of 10-200 nm. The first and the second electrode are partially transparent for electromagnetic radiation and another first and/or the second electrode are partially reflected for the electromagnetic radiation. The first electrode is transparent electrode. The first electrode is subjected on the carrier. The n-semiconductive metal oxide comprises zinc oxide or titanium oxide, and comprises n-semiconductive metal oxide in nanoparticle or amorphous form. The n-semiconductive metal oxide comprises a nonporous layer. The n-semiconductive metal oxide comprises a first metal oxide, which is coated on a non-oxidized semiconductor material with gallium phosphide, zinc phosphide or tin phosphide. The dye comprises stabilization material. The dye has an absorption maximum of 400-700 nm. The dye solar cell has a passivation material between the n-semiconductive metaloxide and the p-semiconductor. The passivation material is arranged to partially prevent the electron transfer between the semiconductive metaloxide and the p-semiconductor. The organic solar cell comprises p-n-mixing material. The organic solar cell has an absorption maximum of 600-1000 nm and has a blocking layer, which is arranged between the second electrode and a further material of the organic solar cell. An INDEPENDENT CLAIM is included for a method for the production of photovoltaic element.    DESCRIPTION OF DRAWING(S) - The figure shows a tandem photovoltaic cell.
