<p>A photovoltaic element (110) for converting electromagnetic radiation into electrical energy is provided, which has a tandem cell structure. The tandem cell structure comprises the following: a dye solar cell (126) having a first electrode (118), an n-type semiconducting metal oxide (120), a dye (122) absorbing electromagnetic radiation in a first spectral range and a solid p-type semiconductor (124); and an organic solar cell (130) having an acceptor material (132) and a donor material (134), the acceptor material (132) and/or the donor material (134) comprising an organic material, the organic solar cell (130) furthermore comprising a second electrode (138) on an opposite side from the dye solar cell (126), and the organic solar cell being configured to absorb electromagnetic radiation in a second spectral range, which is at least partially different to the first spectral range, the first electrode (118) and/or the second electrode (138) being at least partially transparent for the electromagnetic radiation.</p> |
