Pin-probe bar for busbar-free solar cell production

Japan*s Kopel has developed a device with a thickness of just 1.2 mm, with contacts on all of the finger electrodes of busbar-less solar cells.Japan's Kyoshin Electric (Kopel) has developed a pin-probe bar to manufacture contacting systems for busbar-less solar cells. The FSS4 probing solution is also suitable for multi-busbar, half/triple cut and shingled structures. "FSS4 is thinner than conventional pin-probe bars, which reduces its shadow on the cell during the measurement," a spokesperson from the company told pv magazine. "It includes independent current and voltage probes." It said the ...
