1. A solar cell module, comprising:
at least four module segments (1, 2, 3, 4);
a plurality of bypass elements;
each of the four module segments (1, 2, 3, 4) includes at least two solar cell strings connected in parallel and each of the solar cell strings (6) includes a plurality of solar cells connected in series and the four module segments (1, 2, 3, 4) are connected in series;
a second and a third of the four module segments (1, 2, 3, 4) are connected in series between a first and a fourth of the four module segments;
the four module segments are arranged in two parallel series, having a first series, which includes the first and the second module segments (1, 2), and a second series, which includes the third and the fourth module segments (3, 4);
a first bypass element (12) is connected in parallel to the first module segment (1), a second bypass element (13) is connected in parallel to the second and third module segments (2, 3) connected in series, and a third bypass element (14) is connected in parallel to the fourth module segment (4);
wherein at least one of the module segments (1, 2) includes at least two partial segments having at least two of the solar cell strings connected in parallel and the module segment includes a segment cross connector (21, 22), which is arranged between the partial segments of the module segment (1, 2), to form a series connection of the partial segments; and
a first cross connector (7) for parallel connection of the solar cell strings of at least one of the first module segment or the second module segment arranged between first and second module segment (1, 2), a second cross connector (8) for parallel connection of the solar cell strings of at least one of the third module segment or the fourth module segment arranged between third and fourth module segment (3, 4), and the second bypass element (13) is connected between the first and the second cross connector.
