Abstract: The present invention relates to a solar module (1) comprising at least two solar cells (3, 5), wherein each of the solar cells (3, 5) comprises an upper end (21), a lower end (23) which is situated opposite the upper end (21), two opposite side ends (25, 27) and at least one busbar (11, 13) which extends from the first side end (25) to the opposite second side end (27) of the solar cell (3, 5), wherein at least one finger (7, 9) of the solar cell (3, 5) makes electrical contact with the busbar (11, 13), wherein at least one first busbar (11) of at least one first solar cell (3) is arranged at a first side end (25), which is situated opposite a second side end (27) of at least one second solar cell (5) which is arranged or can be arranged next to the first solar cell, at a first distance from the upper end (21) of the at least one first solar cell (3), and at least one second busbar (13) of the at least one second solar cell (5) is arranged at the second side end (27) at a second distance from the upper end (

Abstract: A solar module rear side encapsulation element having a laminate-type layer construction having at least one polymer plate or polymer foil having a laminate surface. The laminate-type layer construction has at least one protective layer having layer openings. The protective layer covers at least 70% of the laminate surface by a covering area, and due to the layer openings at least 15% and maximum 99.9% of the regions of the solar module rear side encapsulation element lying under the protective layer are covered in the covering area, and the protective layer is formed as a structure made of threads, thus being open to diffusion.

Abstract: 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.
