Abstract

See full text

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 (1531) arranged in a parallel finger region (105) and second finger electrodes (1532) arranged in a palm finger region (106). The first finger electrodes (1531) are substantially parallel to each other and perpendicular to the bus bar electrodes (152). The second finger electrodes (1532) 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 (1532) originates from a same associated bus bar electrode (152) and neighboring second finger electrodes (1532) 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.
