1. A solar cell having a front surface and a rear surface, each extending between a first edge portion of the solar cell and a second, opposite, edge portion of the solar cell;
the front surface including one or more front busbars, each front busbar extending in a direction defined by an axis extending between the first and second edge portions of the solar cell and each front busbar including first and second end sections that terminate respectively at first and second ends of the front busbar, wherein a conductive width of the front busbar except the first and second end sections is constant, a conductive width of the first and second end sections of each front busbar is smaller than a full width of the front busbar, as measured in a direction transverse to the axis extending between the first and second edge portions of the solar cell, and the conductive width of the first and second end sections of the front busbar is reduced, proximal to the first and second edge portions of the solar cell respectively, wherein each front busbar is for forming a front electro-mechanical bond with a front side connector that is adapted to interconnect the solar cell with one or more further solar cells, wherein the front electro-mechanical bond between the front side connector and each front busbar has a first front bonding end point at the first end section of the front busbar and a second front bonding end point at the second end section of the front busbar, which first and second bonding end points are respectively adjacent but spaced from the first and second edge portions of the solar cell;
the rear surface including one or more rear electrodes or rear electrode arrays, the rear electrode or rear electrode array for forming a rear electro-mechanical bond with a rear side connector that is adapted to interconnect the solar cell with one or more further solar cells, wherein the rear electro-mechanical bond between the rear side connector and the rear electrode or rear electrode array has a first rear bonding end point and a second rear bonding end point which are respectively adjacent but spaced from the first and second edge portions of the solar cell;
wherein the one or more front busbars, and the one or more rear electrodes or rear electrode arrays, are positioned to:
define locations of the first front bonding end point and the first rear bonding end point such that a distance between the first front bonding end point and the first edge portion of the solar cell is substantially equal to a distance between the first rear bonding end point and the first edge portion of the solar cell, and
define locations of the second front bonding end point and the second rear bonding end point such that a distance between the second front bonding end point and the second edge portion of the solar cell is substantially equal to a distance between the second rear bonding end point and the second edge portion of the solar cell.
