Abstract: Back side connection layer for a photo-voltaic module comprising a plurality of PV-cells (i,j), the plurality PV-cells (i,j) being of a type having one or more back side contacts and divided in a preset number of strings (3) of series connected PV-cells (i. j). By-pass diodes are connectable in parallel to each of the preset number of strings (3), and three or more strings (3) are provided. The plurality of PV-cells (i,j) are positioned such that electrical connections to the first PV-cell and last PV-cell of each of the preset number of strings (3) are provided in a part of the back side connection layer overlapping a part of a two-by-two arrangement of PV-cells (i,j).

Abstract: Back side connection layer for a photo-voltaic module with a plurality of PV-cells. The PV-cells are of a type having a plurality of back side contacts. A by-pass diode connection path is formed in the back side connection layer along an edge direction of two adjacent cells with a straight or meandering pattern around outer contacts of the plurality of back side contacts of the two adjacent cells.

Abstract: Back side connection layer for a photo-voltaic module with a plurality of PV-cells (1, 2). The PV-cells (1, 2) are of a type having a plurality of back side contacts (11, 12). A by-pass diode connection path (6) is formed in the back side connection layer (3) along an edge direction of two adjacent cells (1, 2) with a straight or meandering pattern around outer contacts (4, 5) of the plurality of back side contacts (11, 12) of the two adjacent cells (1, 2).

Abstract: A method for manufacturing a solar cell module that includes a solar cell based on a semiconductor substrate with front and rear surfaces, includes—fabricating a solar cell from the substrate, and—depositing on at least the rear surface a coating layer. The deposition step includes applying a coating powder on at least the rear surface, forming an adhered powder layer on said surface. The method includes after the deposition step: performing a first annealing process on the solar cell module for transforming the adhered powder layer in a pre-annealed coating layer. Further the method includes—creating open contacting areas on the solar cell by removal of the adhered powder layer at locations of contacting areas on the solar cell , wherein the removal precedes the first annealing process, or by masking contacting areas on the solar cell 1, wherein the masking precedes the deposition step.

Abstract: Corrosion effects in a solar cell are measured by means of a conduit with electrolytic fluid. The rim of an open end of the conduit is placed against the surface of the solar cell to expose a selected area of the solar cell to the electrolytic fluid, leaving a free part of the planar surface of the solar cell outside the exposed area. Current and/or voltage fluctuations are measured in an electric circuit that contains the electrolytic fluid, an interface between the electrolytic fluid on the exposed area and a conductor layer on the planar surface, and a contact to the conductor layer in the free part.
