Abstract (en)
[origin: WO2012150529A1] A photovoltaic element (110) for conversion of electromagnetic radiation (130) to electrical energy is proposed, comprising at least one first electrode (116), at least one n-semiconductive metal oxide (120), further comprising at least one dye (112) for absorption of at least a portion of the electromagnetic radiation (130), further comprising at least one organic hole conductor material (126) and at least one second electrode (132). The organic hole conductor material (126) in said photovoltaic element (110) has an absorption spectrum for the electromagnetic radiation (130) which has an absorption maximum in an ultraviolet or blue spectral region and then, toward higher wavelengths, an absorption edge declining with the wavelength of the electromagnetic radiation (130) and having a characteristic wavelength ?HTL. A decadic absorbance of the hole conductor material (126) at a wavelength ?HTL within the declining absorption edge is 0.3. The photovoltaic element (110) further has at least one longpass filter (128). The longpass filter (128) has a transmission edge rising with the wavelength of the electromagnetic radiation (130) and having a characteristic wavelength ?LP, a transmission of the longpass filter (128) at ALp being 50% of a maximum transmission of the longpass filter (128), where ?HTL - 30 nm = ?LP = ?HTL + 30 nm.
