Abstract: A solar module with a front side surface and a rear side surface, has a front side encapsulation element which forms the front side surface of the solar module, a multiplicity of solar cells which are connected electrically to one another, a rear side encapsulation element which forms the rear side surface of the solar module with a rear side surface plane and has a polymer plastic film, and at least one plug-in device connecting to a complementary structure. The plug-in device is at least partially laminated into the rear side encapsulation element, in the region of an overlapping section, wherein the rear site encapsulation element has an opening and the plug-in device is arranged at least partially in the opening. The plug-in device projects beyond the rear side surface plane of the solar module by a maximum of 15 mm.

Abstract: The invention relates to a solar-cell marking method comprising the steps of: providing a substrate with a substrate surface for producing a solar cell (1) that comprises an active zone (5); and producing at least one indentation (21, 31) in the substrate surface with the use of laser irradiation, wherein the at least one indentation (21, 31) forms a marking (2, 3) for marking the solar cell (1), and producing the indentation (21, 31) is carried out prior to carrying out a solar-cell manufacturing process or during carrying out a solar-cell manufacturing process. According to the invention the substrate is designed as a semiconductor wafer with a wafer surface, and the marking (2, 3) is positioned on the wafer surface such that the marking (2, 3) is in the active zone (5) of the solar cell (1) formed by the semiconductor wafer.
