摘要： A solar module and a method for fabricating a solar module comprising a plurality of rear contact solar cells are described. Rear contact solar cells (1) are provided with a large size of e.g. 156×156 mm2. Soldering pad arrangements (13, 15) applied on emitter contacts (5) and base contacts (7) are provided with one or more soldering pads (9, 11) arranged linearly. The soldering pad arrangements (13, 15) are arranged asymmetrically with respect to a longitudinal axis (17). Each solar cell (1) is then separated into first and second cell portions (19, 21) along a line (23) perpendicular to the longitudinal axis (17). Due to such cell separation and the asymmetrical design of the soldering pad arrangements (13, 15), the first and second cell portions (19, 21) may then be arranged alternately along a line with each second cell portion (21) arranged in a 180°-orientation with respect to the first cell portions (19) and such that emitter soldering pad arrangements (13) of a first cell portion (19) are aligned with base soldering pad arrangements (15) of neighboring second cell portions (21), and vice versa. Simple linear ribbon-type connector strips (25) may be used for interconnecting the cell portions (19, 21) by soldering onto the underlying aligned emitter and base soldering pad arrangements (13, 15). The interconnection approach enables using standard ribbon-type connector strips (25) while reducing any bow as well as reducing series resistance losses.

摘要： 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.
