Abstract: A solar panel is provided with a stack including at least one back contacted solar cell and a back-sheet layer. The back-sheet layer has a patterned conductive layer of a first material. The conductive layer is arranged with contacting areas each located at a location corresponding to a location of an electrical contact on the solar cell. The solar cell is arranged on top of the conductive layer with the rear surface of the solar cell facing the patterned conductive surface. Each electrical contact of the solar cell is in contact with a corresponding contacting area on the conductor circuit by a body of conductive connecting material. The conductive layer includes at the location of the contacting area a patch of a second material. Each patch is arranged in between the body of conductive connecting material on one electrical contact and the layer of the first material.

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.
