1. A method of shingling solar cells, the method comprising:
providing a solar cell having a front metallization pattern and a rear metallization pattern;
cutting the solar cell to form first and second solar cell strips so that each solar cell strip has a portion of the front metallization pattern and a portion of the rear metallization pattern of the solar cell;
attaching front-side ribbons to the first solar cell strip so that the front-side ribbons contact the front metallization pattern of the first solar cell strip, attaching front-side ribbons to the second solar cell strip so that the front-side ribbons contact the front metallization pattern of the second solar cell strip;
attaching rear-side ribbons to the first solar cell strip so that the rear-side ribbons contact the rear metallization pattern of the first solar cell strip, attaching rear-side ribbons to the second solar cell strip so that the rear-side ribbons contact the rear metallization pattern of the second solar cell strip, the rear-side ribbons are separate from the front-side ribbons, the rear-side ribbons having a cross-sectional width that is at least 2 times larger than a cross-sectional width of the front-side ribbons; and
after attaching the front-side ribbons and after attaching the rear-side ribbons, assembling the first and second solar cell strips in a shingled manner to create an overlap area so that the rear-side ribbons extend into the overlap area and the front-side ribbons do not extend into the overlap area.
