The invention relates to a cover element, in particular a lid, for a junction box of a solar module, wherein the cover element forms upper and undersides that are mirror-symmetrical in terms of its geometrical form, and wherein at least one first marking is applied to the upper side and/or at least one first marking is formed via the upper side in the form of an indentation and/or elevation, and at least one second marking is applied to the underside and/or at least one second marking is formed via the underside in the form of an indentation and/or elevation, wherein the at least one first marking is not identical to the at least one second marking and/or the cover element comprises a rotational joint or a part of a rotational joint and/or is/can be operatively connected to a rotational joint, such that the lid is/can be mounted so that it can be horizontally rotated about the rotational axis of the rotational joint. The invention also relates to an assembly of the cover element and junction box, and to a use thereof.

Cover element for a junction box of a solar module

A solar cell includes a semiconductor wafer, at least one dielectric layer arranged on the semiconductor wafer, a metal layer arranged on the dielectric layer, and a contact structure arranged in the dielectric layer such that the contact structure provides an electrical connection between the metal layer and the semiconductor wafer. The contact structure has at least one first structure having a minimum dimension and at least one second structure having a maximum dimension, wherein the minimum dimension and the maximum dimension are defined along a surface of the semiconductor wafer and the minimum dimension of the first structure is greater than the maximum dimension of the second structure.
