Abstract: The invention relates to an arrangement and circuit, and to a method for interconnecting flat rigid or flexible solar cells, the photoelectrical active layers thereof being applied to an insulating substrate material. The aim of the invention is provide a novel arrangement and circuit and an associated method for interconnecting flat solar cells, reducing the risk of short circuit and the inactive surface area in the matrix composite of the solar module and selectively allowing simple interconnection, both as a parallel circuit and as a series circuit in production. The solar cells (1) in the arrangement and circuit of flat rigid or flexible solar cells are disposed overlapping in the contact area to one or more adjacent solar cells (1). Said solar cells (1) are interconnected to each other directly once or a plurality of times in a novel manner, having a contact material (10) at the overlapping area to each other, used in contact material (10) or switching points (22).

Abstract: The invention relates to a panel form photovoltaic frameless solar module, in particular, a large surface solar module having increased stability and strength. The aim of the invention is to produce the panel form photovoltaic solar module which is insensitive to rough climatic effects of the weather as well as effective at diffusing very high mechanical stresses in the substructure. A planar light weight reinforcement structure (5) is at least partially stuck directly to the reverse side of the material (4), for planar or curved solar modules, in the inventive panel form photovoltaic frameless solar module (1) which comprise solar cells (3), which are embedded between cover side of the material (2) and the reverse side of the material (4). Said light weight reinforcement structure (5) is embodied entirely or partially on at least two sides as a supporting frame structure (6), that is additionally reinforced.
