Abstract

The solar cell connector electrode (400) has several electrically conductive solar cell connector elements (302) that are arranged adjacent to each other. The electrically conductive solar cell connector elements are arranged on the electrically non-conductive planar elements (304) that are separated from each other. Solar cell connector element interfaces (306) are provided at the regions on the planar elements, so that solar cell connector elements are divided into several electrically separated solar cell connector sub elements (402,404). Independent claims are included for the following: (1) solar cell module; and (2) method for electrically connecting several solar cells.

Description

technical field [0001] Embodiments relate to solar cell connector electrodes, solar cell modules, and methods of electrically connecting a plurality of solar cells. Background technique [0002] Different back contact solar cell concepts are known: [0003] - Metal Wrap-Through (MWT) solar cells; [0004] - Emitter Wrap-through (EWT) solar cells, wherein MWT solar cells and EWT solar cells are disclosed in Haverkamp et al., 19th European Photovoltaic Solar Energy Conference, June 7 to 11, 2004, Paris, France; and [0005] Back-junction solar cells are disclosed in DE 195 25 720 A1. [0006] The advantage of the back contact solar cell is mainly to reduce the shading on the solar surface of the solar cell. Both base and emitter contacts are applied to the back side of the solar cell. In this case, various layouts are known. [0007] One possibility is a strip arrangement of the contacts on the back of the solar cell. Another approach provides two metallization structure...
