Allegro Series

Allegro laser systems are used for all processes associated with laser structuring (laser scribing) thin-film solar cells. Whether CIGS, CIS, aSi, aSi/µSi or CdTe, depending on the actual thin-film technology Allegro systems are equipped with the corresponding optimal laser sources and can be equipped for machining from the film- or non-film side of glass. The building block system accommodates various substrate sizes. The Allegro series combines the ultimate performance and profitability in laser structuring.

Ultimate output

The motion of the dynamically optimal component, a compact machining head with multiple parallel machining beams, allows for maximum acceleration and speed to reduce the machining time inside the Laser Scriber. A single machining step simultaneously delivers multiple structures, and substrate handling processes are parallelized to the greatest extent possible. This increases machine output while reducing production costs.

Maximum module efficiency

The cell with the lowest performance significantly determines the module’s performance. It’s therefore important to produce a high-precision layout with uniform cell size distribution in step P1. The subsequent P2 and P3 lines are accurately aligned and positioned based on this master. An ultra-precision P1 Allegro and the Dynamic Path Tracking in the P2 and P3 Allegros reduce the “dead zone” to maximize module output.

Optimum availability

From a construction perspective Allegro laser scribers are  rugged, low-maintenance and designed to be easy to maintain: with maintenance-free air bearings for transporting glass and moving the machining head, long-life laser sources and preset optical and mechanical components. This effectively reduces scheduled and unscheduled non-production times, increasing system availability.

Cost efficiency

Optimized machine dynamics, accurate structuring and the minimum-cost machine design make the Allegro laser scriber particularly profitable production equipment for thin-film solar modules.
