摘要:
A high efficiency configuration for a solar cell module comprises solar cells arranged in an overlapping shingled manner and conductively bonded to each other in their overlapping regions to form super cells, which may be arranged to efficiently use the area of the solar module.

Solar cells having a plurality of sub-cells coupled by metallization structures having a metal bridge, and singulation approaches to forming solar cells having a plurality of sub-cells coupled by metallization structures, are described. In an example, the metal bridge can provide structural support and provide for an electrical connection between a first contact pad and a first busbar. Adjacent ones of the singulated and physically separated semiconductor substrate portions have a groove there between and where the metal bridge can be perpendicular to the groove. The solar cell can include a first contact pad adjacent to a second contact pad.

A solar cell (104) is disclosed. The solar cell includes a substrate (151) including a front surface (156) and front surface electrodes (153) extending along the front surface (156). Therein, the front surface electrodes comprise a plurality of bus bar electrodes (152) coupled to a plurality of first finger electrodes (153 1 ) arranged in a parallel finger region (105) and second finger electrodes (153 2 ) arranged in a palm finger region (106). The first finger electrodes (153 1 ) are substantially parallel to each other and perpendicular to the bus bar electrodes (152). The second finger electrodes (153 2 ) originate from end regions of the bus bar electrodes (152) and radially extend at least in portions thereof in directions non- perpendicular to the bus bar electrodes (152). Therein, a palm-like group of neighboring second finger electrodes (153 2 ) originates from a same associated bus bar electrode (152) and neighboring second finger electrodes (153 2 ) radially extend at different angles with respect to the bus bar electrodes (152). With such electrode configuration, shading losses as well as electrical resistance losses may be reduced.
