Tandem photovoltaic cell

A photovoltaic element for converting electromagnetic radiation into electrical energy, the photovoltaic element having a tandem cell structure, wherein the tandem cell structure comprises:

• a dye solar cell having a first electrode, an n-type semiconducting metal oxide,
• a dye absorbing electromagnetic radiation in a first spectral range and a solid p-type semiconductor;
• and
• an organic solar cell having an acceptor material and a donor material, the acceptor material and/or the donor material comprising an organic material, the organic solar cell furthermore comprising a second electrode on an opposite side from the dye solar cell, and the organic solar cell being configured to absorb electromagnetic radiation in a second spectral range, which is at least partially different from the first spectral range,
• the first electrode and/or the second electrode being at least partially transparent for the electromagnetic radiation,
• wherein the photovoltaic element comprises at least one charge recombination zone between the dye solar cell and the acceptor material of the organic solar cell.
