Abstract
A photovoltaic element including a number n of cells arranged on a substrate, from a first cell to an n-th cell and at least one busbar connected to the first cell and/or the n-th cell by an electrically conductive contacting. The cells each have a bottom electrode, a top electrode and a layer system including at least one photoactive layer. The layer system is arranged between the bottom electrode and the top electrode, and the cells are interconnected in series among one another. The electrically conductive contacting is formed by via points arranged in each case at specific distances A from one another in a longitudinal direction of the at least one busbar. No electrically conductive contacting is formed between the top electrode and the at least one busbar in regions between individual via points.
