An interconnect is formed through the island, using the island as an alignment fiducial. The island and the interconnect are isolated from the remainder of the first conductive layer.

Photovoltaic devices with conducting layer interconnects

According to the embodiments provided herein, a method for scribing a layer stack of a photovoltaic device can include directing a laser scribing waveform to a film side of a layer stack. The laser scribing waveform can include pulse groupings that repeat at a group repetition period of greater than or equal to 1.5 &#x3bc;s. Each pulse of the pulse groupings can have a pulse width of less than or equal to 900 fs.
