Abstract
A multi-step scribing operation is provided for forming scribe lines in solar panels to form multiple interconnected cells on a solar panel substrate. The multi-step scribing operation includes at least one step utilizing a nanosecond laser cutting operation. The nanosecond laser cutting operation is followed by a mechanical cutting operation or a subsequent nanosecond laser cutting operation. In some embodiments, the multi-step scribing operation produces a two-tiered scribe line profile and the method prevents local shunting and minimizes active area loss on the solar panel.
