Highly efficient and cost-effective laser processing of thin-film modules

Our Allegro systems are unmatched in terms of throughput, availability and accuracy in the market. We are constantly developing these laser scribing systems further. Being a supplier to the most advanced thin-film technologies drives and pushes us to constantly improve our systems with regard to throughput and accuracy as well and being equally important for manufacturer in terms of system uptime. One major part of maintaining uptime is our well organized 24/7 service support in the countries where production takes place.

Application examples of scribing processes

LPKF develops processes and optimizes parameters for all scribing tasks in CdTe, aSi, aSi/µSi, CIS, CIGS technologies, taking into account cost-efficiency and technological aspects. Our application labs feature a variety of laser sources, near-productions system technologies and analytical systems such as SEM and Laser Scanning Microscope. In this way customer applications can be implemented.

CIGS P1

Molybdenum with barrier layer processing with optimized pulse duration: No glass damage, no cracks in the glass, no barrier layer damage, no burr

CIGS P2

Selective absorber removal using ultra-short laser pulses

CIGS P3

Front contact removal with ultra-short laser pulses

Deadzone in CIGS

160µm deadzone achieved with Allegro Scribers

Laser structuring of thin-film modules

High performance Allegro systems for 24/7 production and Presto lab system

Our Allegro laser scribing systems are unmatched in terms of throughput, availability and accuracy. Being a supplier to the most advanced thin-film module manufacturers drives us to constantly improve our systems with regard to throughput and accuracy as well system uptime.
To support R&D in universities and module manufacturing companies LPKF has developed the Presto lab scale scriber for mini modules, delivering the same performance in terms of speed and accuracy as the Allegro systems, but providing the flexibility to test new laser sources and parameters for process optimization and maximized module efficiency.
