Front and back side of a 156 × 156 mm polycrystalline silicon solar cell to be cut into four QuarterCells. The cuts by laser are done in the three non-metallized stripes at the back, and do not go through the wafers. The final separation is done by breaking along the laser lines. This also breaks the screen printed front bus bars in two (several types of metallization have been tried, the one shown here is called QuarterCell “P”).
