Abstract: The invention relates to a method for production of a serial circuit of solar cells with integrated semiconductor bodies, a serial circuit produced thus and photovoltaic modules, comprising at last one serial circuit. The invention is characterized in that conducting bodies (20) and semiconducting bodies (30) are applied to an insulating support layer, according to a pattern, whereby said pattern provides at least one dividing line (21) of conducting bodies. The regions adjacent to the conducting bodies are provided with spherical or particle-shaped semiconducting bodies (30). Parts of the semiconductor bodies are removed and the support layer coated on the side with a back contact layer (50). The back contact layer of a semiconducting body is thus exposed, for example, and brought into contact with the back contact layer (50) of the solar cell. The other side of the support layer (10) is provided with a front contact layer.

Abstract: The invention relates to a device for the targeted application of deposition material onto a substrate, especially for focusing the sputter flux onto a narrow angular range in a PVD-system. The invention is characterized in that the deposition material is directed through a filter structure (90) having several channel-shaped individual structures (60) onto said substrate (30), whereby the streams of material are limited to a narrow angle range.

Abstract: A spherical or grain-shaped semiconductor element for use in solar cells and to a method for producing the semiconductor element. Also disclosed is a solar cell including an integrated spherical semiconductor element, a method for producing the solar cell, and a photovoltaic module including at least one solar cell. The semiconductor element includes a back contact layer and a I-III-VI compound semiconductor deposited on a spherical or grain-shaped substrate core. The I-III-VI compound semiconductor is produced by applying precursor layers and subsequent selenization or sulfurization. For producing a solar cell, a plurality of the inventive semiconductor elements is introduced into a substrate layer from which they project on at least one face thereof. The substrate layer is striped on one side, thereby exposing the back contact layer of most of the semiconductor elements.
