We evaluate industrial‐type PERC solar cells applying a 5 busbar front grid and fineline‐printed Ag fingers. We obtain finger widths down to 46 µm when using a stencil with 40 µm opening for the finger print, whereas the busbar is printed in a separate printing step with a different Ag paste (dual print). This compares to finger widths of 62 …

Even though the higher quantity of busbars increases the shading of the solar cell, yet the overall performance of multi-busbar cells is much better than that of conventional 2BB or 3BB cells. Why is that so? Key aspects are the reduction of the effective finger length between the busbars, which reduces finger resistance losses, as well as the lesser …
