Claim 0:
1. A device comprising:
a string of solar cells comprising at least a first and second rectangular or substantially rectangular crystalline silicon solar cells electrically connected in series, each crystalline silicon solar cell comprising:
a front surface having a front metallization pattern comprising a plurality of front conductive fingers oriented parallel to a long edge of the front surface;
a front pad disposed on the front surface and located at the long edge of the front surface, the front pad electrically connected to the front metallization pattern;
a front-side ribbon disposed on the plurality of front conductive fingers and on the front pad, the front side ribbon oriented parallel to a short edge of the front surface and having a cross-sectional width;
a rear surface having a rear metallization pattern comprising a plurality of rear conductive fingers oriented parallel to a long edge of the rear surface; and
a rear-side ribbon separate from the front-side ribbon; the rear-side ribbon disposed on the plurality of rear conductive fingers, the rear side ribbon having a cross-sectional width that is at least 2 times larger than the cross-sectional width of the front side ribbon;

the first and second solar cells arranged in a shingled manner with long sides of the first and second solar cells overlapping to create an overlap area, the rear-side ribbon of the first solar cell in contact with the front pad of the second solar cell, the rear-side ribbon extending into the overlap area, the front-side ribbon not extending into the overlap area.
