Versatile thin-film photovoltaic laser scribing system

We present a laser scribing system for mid-size photovoltaic modules (up to 410 × 520 mm2) implementing a movable diode-pumped solid state laser. In this configuration, the heavy large-area photovoltaic module does not need to be displaced, allowing for faster and overall more compact industrial systems. Furthermore, in the vicinity of the thin-film, critical beam parameters such as the depth of focus are kept constant throughout the scribing process.
