Embodiment Construction

[0118] According to the figures, which in principle use the same reference numbers for the same elements, the teaching according to the invention will be explained in terms of solar cells wired in series to form modules.

[0119] From figure 1 A corresponding module 10 can be seen in the plan view of , wherein in the exemplary embodiment—without limiting the scope of protection—four solar cells 12 are arranged and wired on a carrier 14 .

[0120] In the description of this embodiment, metal foam is cited as material for the carrier 14, without thereby limiting the teaching according to the invention, but foam material is cited as a preferred carrier material due to its inherent rigidity, good thermal conductivity and low weight .

[0121] In particular, the carrier 14 can also be made of an electrically insulating material, such as cardboard or cardboard made of cellulose and / or waste paper. Other suitable materials are likewise conceivable, such as plastic foam or fabric a...

Abstract

The invention relates to a solar cell module, comprising solar cells (13, 15) that are arranged on a mount (14) and connected by means of connectors (24, 26). In order to be able to produce the solar cell module at low cost and to minimize the electrical losses due to connectors, the mount is provided with recesses (22), within which the connectors extend at least in some sections, and the solar cells are arranged outside of the recesses in a planar manner or substantially planar manner on the mount or on a layer extending on the mount.

Description

technical field [0001] The invention relates to a solar cell module comprising solar cells arranged on a carrier, the solar cells being connected by means of connectors. The invention also relates to a method for wiring solar cells having first and second contacts to form a module, wherein the solar cells are arranged on the rear side on a carrier having first and second electrical connections Through the electrical connector, the solar cell is wired at a connection point with its first and second contact portions. Background technique [0002] In order to utilize solar cells to provide suitable voltage or power, it is known to wire the solar cells into larger units. To produce a corresponding module, the cells are connected to one another in parallel or in series and embedded in a suitable transparent encapsulation material, such as ethylene vinyl acetate (EVA). On the front side, the corresponding modules are usually covered by a glass pane and on the rear side by a weat...
