1. A device comprising:
a string of solar cells comprising
at least first and second substantially rectangular crystalline silicon solar cells electrically connected in series, each solar cell comprising front and rear surfaces each having a metallization pattern, a first long side having a corrugated shape with protruding portions and recessing portions, and a second long side; the first and second solar cells arranged in a shingled manner with the protruding portions of the first long side of the second solar cell overlapping with the second long side of the first solar cell;
an opening comprising one of the recessing portions of the first long side of the second solar cell; and
an electrically conductive ribbon passing through the opening connecting the front surface metallization pattern of the second solar cell with the rear surface metallization pattern of the first solar cell.
