Abstract

Embodiments of the invention provide a photovoltaic module, a method for electrically connecting a plurality of photovoltaic cells, and a device for electrically connecting a plurality of photovoltaic cells. In various embodiments, the photovoltaic module may include: a plurality of photovoltaic cells, at least one photovoltaic cell of the number of photovoltaic cells comprising: a first plurality of contact wires on a front of the photovoltaic cell; and a second plurality of contact wires on a rear of the photovoltaic cell. The first plurality of contact wires and the second plurality of contact wires may be arranged offset with respect to one another.

Description

technical field [0001] Various embodiments of the invention relate to a photovoltaic module, a method for electrically connecting a plurality of photovoltaic cells, and an apparatus for electrically connecting a plurality of photovoltaic cells. Background technique [0002] Photovoltaic cells, such as solar cells, typically have a layer of semiconducting material, such as silicon, also referred to hereinafter as photovoltaic layer. The photovoltaic layer has a front side (also called emitter side) and a back side, wherein (conductive) contact patterns (for example in the form of so-called contact fingers) are applied to the sides in both sides. At least one up. The contact pattern typically has a width of at least 100 μm, while its thickness is only about 10 μm to 15 μm. Larger contact pattern widths lead to reduced efficiency due to the increased amount of shading produced, while reduced widths lead to the disadvantage of increased line resistance of the contact pattern. ...
