    • A photovoltaic element for conversion of electromagnetic radiation to electrical energy, having at least one first electrode, at least one n-semiconductive metal oxide, at least one dye for absorption of electromagnetic radiation, at least one organic hole conductor material, and at least one second electrode. The organic hole conductor material has an absorption spectrum which has a maximum in the ultraviolet or blue spectral region and, toward higher wavelengths, an absorption edge declining with wavelength and having a characteristic wavelength λHTL. A decadic absorbance of the hole conductor material at a wavelength λHTL within the declining absorption edge is 0.3. The photovoltaic element includes a longpass filter, which has a transmission edge rising with wavelength and having a characteristic wavelength λLP. A transmission of the longpass filter at λLP is 50% of a maximum transmission of the longpass filter, where λHTL−30 nm≦λLP≦λHTL+30 nm.
