Disclosed is a solar cell having at least one photovoltaic layer (A) made of an organic material, in particular a polymer material, which absorbs light and in which electron-hole pairs can be produced, said solar cell having two opposite layer surfaces of which one is connected with at least one hole-receiving layer (p) produced inside said photovoltaic layer (A) and the other is connected with at least one electron-receiving layer (n) produced inside said photovoltaic layer (A), as well as having electrode areas En and Ep, of which one said electrode area (Ep) is electrically contacted to said hole-receiving layer (p) and the other said electrode area (En) is electrically connected to said electron receiving layer (n). The invention is distinguished by the electron-receiving layer (n) being connected via its electrode area (En) to a flat substrate (S) having a front side and a rear side, by the flat substrate (S) being provided with opening structures (O) projecting laterally through from said front side to said rear side, by the hole-receiving layer (p), the photovoltaic layer (A), the electron-receiving layer (n) and the electrode area (En) connected to said layer (n) being applied on said front side of the flat substrate (S) in such a manner that at least single opening structures project laterally through the flat substrate (S) and through the layer system comprising the layers En, n, A, and p, by an electrically conducting p<SUP>++</SUP> layer being applied onto the hole-receiving layer (p) or the hole-receiving layer (p) being designed as a p<SUP>++</SUP> layer which at least partially fills the opening structures (O) projecting laterally through the flat substrate (S) to the rear side of said flat substrate (S), and by the electrode area (Ep) for receiving the hole-receiving layer (p) being provided on the rear side of the flat substrate (S), the electrode area (Ep) being electrically contacted to the p<SUP>++</SUP> layer reaching through the opening structures (O).
