Abstract
The invention relates to a photovoltaic device (1), comprising a photovoltaic acceptor material (7) and a photovoltaic donor material (10), in which the photovoltaic device (1) comprises at least two carrier layers (2, 3), of which one carrier layer (2) has n-doped electron donors (6) and the other carrier layer has acceptor material (7) as p-doped or undoped electron acceptors, wherein the carrier layers (2, 3) are arranged with respect to one another such that they touch one another at least in sections, and the carrier layers (2, 3) are wetted or coated in filmlike fashion with a photovoltaic donor material (10). The carrier layers (2, 3), which are formed in particular from fibres (6, 7) composed of silicon carbide SiC, enable textile solar cells. Methods for producing the fibres (6, 7) and for producing the photovoltaic device (1) and textile structures formed therefrom are furthermore described. A photovoltaic device (1) is furthermore proposed, in which carrier elements of an individual carrier layer have a corresponding photovoltaically active construction by virtue of correspondingly applied layers.
