  • Photovoltaic element
    Patent number: 9087991
    Abstract: A photovoltaic element (110) is proposed for conversion of electromagnetic radiation to electrical energy, more particularly a dye solar cell (112). The photovoltaic element (110) has at least one first electrode (116), at least one n-semiconductive metal oxide (120), at least one electromagnetic radiation-absorbing dye (122), at least one solid organic p-semiconductor (126) and at least one second electrode (132). The p-semiconductor (126) comprises silver in oxidized form.
