A photovoltaic element including at least one photovoltaic cell at least partially segmented and having a base electrode, a top electrode, and a layer system comprising at least one photoactive layer, wherein the layer system is arranged between the base electrode and the top electrode, the segments are configured such that at least the top electrode and the layer system of one of the segments are separated from the top electrode and the layer system of another segment by at least one cavity to prevent contact between one another, the at least one cavity is formed substantially vertically relative to the layer system of the at least one photovoltaic cell, and the segments are electrically conductively connected in parallel with one another such that a flow of electric current through the at least one photovoltaic cell is distributed over each of the segments.

Photovoltaic element with improved efficiency in the event of shade, and method for producing such a photovoltaic element

A column with at least one photovoltaic element for converting radiation energy is disclosed. The at least one photovoltaic element converts radiation energy of light, such as sunlight, into electrical energy. The at least one photovoltaic element is arranged on the column, and at least one photovoltaic element is a flexible photovoltaic element.
