“We are pleased to present our laser processing equipment to the Asian prospects at the SNEC 2012,” says Dr. Thomas Fehn, Executive Vice President of Jenoptik’s Lasers & Material Processing division. “Jenoptik’s products for the processing of solar cells are high performers and deliver stable results in standard photovoltaic applications such as silicon ablation or laser edge isolation as well as in many modern innovative technologies.”

Jenoptik’s infrared disk laser with independently adjustable laser parameters for the photovoltaics

To be seen in Shanghai will be the newly introduced infrared disk lasers JenLas® disk IR50E and JenLas® disk IR70E with optimized, independently adjustable laser parameters for the photovoltaic sector. These E-version lasers (E = extended) achieve shorter pulse lengths, significantly higher repetition rates and constantly high pulse energies. Another advantage for the user is that the pulse lengths of the lasers can be adjusted independently of repetition rate and laser power. Standardized interfaces for easy integration and high control flexibility (analog, digital, software) were also an important aspect and have been realized accordingly.

The new JenLas® disk IRxxE lasers particularly meet the requirements of LFC (Laser Fired Contacts) with up to 25,000 contacts per second, MWT (Metal Wrap Through), EWT (Emitter Wrap Through) as well as LEI (Laser Edge Isolation).
Femtosecond laser for optimal use in the photovoltaic industry

Another product to be exhibited is the femtosecond laser JenLas® D2.fs. Based on the disk laser technology, the laser guarantees outstanding parameter stability and sets a new standard for laser sources of the femtosecond technology. The laser emits high pulse energies and can be operated in the high repetition range. The beam quality of M² ≤ 1.25 coupled with the pulse duration of ≤ 400 fs allows innovative industrial laser applications in photovoltaics. To be mentioned is a selective single layer removal in processing of multi-layer systems composed of a variety of materials. The related industrial application is the removal of dielectric layers on crystalline solar cells.

The laser sources JenLas® disk IR50E / IR70E and JenLas® D2.fs have OEM design and are perfectly suitable for integration into every laser machine.

All-rounder for laser structuring of the original sized thin-film solar cells

Jenoptik’s Lasers & Material Processing also presents at SNEC 2012 its latest and globally unique machine generation of JENOPTIK-VOTAN® Solas Multi. This laser machine is a universal mass production system for all structuring processes. It can also be used as an R&D pilot system for optimization of customized thin-film photovoltaic modules. That means that the appropriate lasers are integrated into one machine concept.

JENOPTIK-VOTAN® Solas Multi for structuring and JENOPTIK-VOTAN® Solas LED for edge deletion efficiently process thin-film solar modules of small to very big size. Other applications are mechanical scribing for CIS/CIGS technologies and laser ablation for semi transparent BIPV modules.
