When a technology has been in continuous industrial use for nearly 50 years, it stops being a promise and becomes a track record. That is exactly what LPKF brings to perovskite manufacturing.
LPKF was founded in Hannover, Germany in 1976. Since then, laser processing has been the company's core discipline. Not one application among many. Over five decades, that expertise has been built, tested, and refined across some of the most demanding production environments in the world: PCB manufacturing, automotive, medical technology, semiconductor packaging, glass microprocessing. Different industries. Different materials. The same uncompromising requirement: laser precision at industrial scale.
50 Years of Laser Expertise for Thin-Film and Perovskite Manufacturing
Thin-film module manufacturers needed a solution for one of the most critical steps in their production chain: laser scribing. To manufacture a thin-film solar module, the full layer stack deposited on a large glass substrate must be divided into individual cell segments and interconnected in series. This is done by scribing three precisely defined isolation lines, P1, P2, and P3, directly into the layer stack. The width of these lines, and the accuracy with which they are placed, determines how much of the substrate area actually generates power. Every micrometer counts.
Now, nearly 20 years later, more than 250 systems are running in production fabs across the world. They have processed CdTe, CIGS, Perovskite and OPV modules. They are running in some of the largest thin-film manufacturing facilities in operation. At 97% system availability, they run around the clock.
250 systems. Five decades of laser expertise behind every one of them.
Meet our Allegro Family
The Allegro is not a laboratory instrument scaled up for production. It was designed from the ground up for one environment: a 24/7 manufacturing fab where precision, throughput, and reliability are simultaneously non-negotiable.
The machine base is granite, chosen for its minimal thermal expansion and vibration damping. Moving components run on air bearings, eliminating mechanical wear. The system can operate with up to 24 parallel laser beams, scribing multiple lines in a single pass at speeds of up to 4 m/s. Laser sources are available at 355 nm, 532 nm, and 1064 nm, with pulse durations configurable from nanosecond to femtosecond.
Two proprietary technologies address the core precision challenges. Path Tracking monitors the P1 reference line in real time and aligns P2 and P3 relative to it, correcting for substrate shifts caused by thermal effects between process steps. Dynamic Focus Tracking continuously adjusts the focal position across the full substrate surface, ensuring consistent energy density even on substrates that are not perfectly flat. Both run on the fly, with no impact on cycle time.
These capabilities enable dead zones down to 100 µm, helping maximize active cell area and module performance.
And for perovskite?
Perovskite laser scribing systems are not in development. They are qualified and in the field. Customers are running them in production today. The thermally sensitive layer stacks, the selective ablation requirements, the tight tolerances that determine whether a perovskite module performs in the lab or in a GW-scale fab: these are exactly the process challenges the Allegro was built to handle.
Fifty years of laser expertise. Nearly 20 years in photovoltaics. The Allegro. And perovskite systems already running in the field. That is what LPKF brings to your production line.
