Cost-Effective Production
Profitability counts...
Producing ultra-precise structures on large glass substrates is a challenging task. Thermal deformations arising caused by high-temperature coating processes between laser scribing steps only increase the level of difficulty. Ultra-precise scribing with our Allegros allows module efficiency to be increased as much as physically possible. Innovative, field-tested concepts compensate for virtually any deviations from the optimal cell geometry across the entire process chain and establish the basis for modules with maximum efficiency. Furthermore, Allegro laser scribers are exceptionally economical in terms of overall investment and operation by offering the highest possible throughput.

A solid machine base provides precision, dynamics and reliability. The actual laser scribing is done by the moving laser processing head, the heart of the Allegro system. All major moving components are based on virtually wear-free air bearings. The Allegro implements the concept of moving the dynamically optimal component and combines key functions in a compact design. It arranges up to 12 parallel laser beams and focuses them on the thin-film module. In addition, moving the module in and out while scribing minimizes secondary processing time and maximizes throughput even further. The approach to move the scribing head allows an array of intelligent and cost-effective solutions to maximize the module’s efficiency, minimize the so-called dead zone and stabilize the scribing process. Dynamic Path Tracking reduces the safety clearance required and maximizes module efficiency at minimal technical expense. Wavy substrates from thermal processing or small process windows impair laser scribing results by reducing process stability. Dynamic Focus Tracking keeps every laser beam in its focal plane on the module during scribing. This leads to optimal scribing results on wavy substrates. Integrated sensors allow for an automatic recalibration of the scribing head to ensure accuracy across various production utilization scenarios.
Highly sophisticated technology inside
Thin-film panel factories are continous 24/7 operations demanding technical availabilities of up to 97%. Low operating costs, low maintenance and service friendliness are additional vital factors to achieve cost-effective production in the P1 through P3 laser scribing processing steps and subsequent edge deletion. The LPKF Allegro Series is able to satisfy such demands and specifications. Optimized machine dynamics, precision laser scribing and the minimum-cost machine concept make the Allegro laser scribers an exceedingly cost-effective solution for production thin-film solar modules.
The Allegro Series - Next generation of laser scribing
Your Benefits with proven LPKF technology
A compact, multi-beam head enables maximum acceleration and speed, reducing the laser scriber cycle time.
One scribing head move produces multiple structures at the same time. Substrate handling processes are parallelized to the greatest possible extent, which increases the machine’s throughput and reduces production costs.

The weakest cell greatly impacts the overall performance of the module. Producing an ultra precise layout with uniform cell size distribution in the P1 step is critical. The subsequent P2 and P3 lines are accurately aligned and positioned based on this master.
Using an ultra precise Allegro system for the P1 scribing and Allegro’s Dynamic Path Tracking technology for the P2 and P3 scribing significantly extend the active module area for maximum module efficiency.
