Laser Patterning Equipment

Präzision für die nächste Generation

Maximieren Sie den Wirkungsgrad Ihrer Module mit der fortschrittlichsten Lasertechnologie von DJK Europe. Unsere Lösungen für die Strukturierung von Perowskit-Solarzellen reduzieren die „Dead Area“ um bis zu 66 % und setzen neue Maßstäbe in Präzision und Verarbeitungsgeschwindigkeit.

Why Choose DJK Laser Solutions for PSC?

The efficiency of Perovskite modules depends crucially on minimizing inactive surfaces (Dead Area) and the quality of layer separation. Our systems utilize ultra-short pulse lasers and patented correction technologies to unlock the full potential of PSC technology—on both glass and film substrates.

Advantages

Massive Reduction of the "Dead Area":
Decreased from 540 µm to just 180 µm (approx. 66% savings) for maximum active area.
Ultra-Fine Processing:
Achieving line widths as narrow as 20 µm.
High-Speed Processing:
Speeds of up to 2,000 mm/sec without thermal damage to the underlying layers.
In-House Integration:
From oscillators to optical systems—all core components are perfectly synchroniz

Core Technologies: P1, P2 & P3 Scribing

We provide specialized solutions for all three critical patterning steps in thin-film photovoltaics:

P1 Process: Precise removal of the Transparent Conductive Oxide (TCO) layer.
P2 Process: Patterning of the Perovskite absorber layer.
P3 Process: Processing of the back electrode layer for final cell interconnection.

Intelligent Correction Control (Patented)

Our systems feature real-time image recognition that detects substrate deformations (expansion/shrinkage) and adjusts the laser position instantly. The "Following Correction" recognizes previously patterned lines and guides the laser precisely to minimize gaps and prevent short circuits.

FAQ

By reducing the inactive connection surfaces (Dead Area), the proportion of the active area in the total element increases. Our technology recovers approx. 66% of this lost area, directly boosting the efficiency of the finished module.

Yes, our patented correction technology is specifically designed to compensate for deformations in flexible films in real-time, ensuring maximum precision even in roll-to-roll processes.

No. We use ultra-short pulse lasers that remove the material before heat can flow into the surrounding layers (cold ablation). As a result, the sensitive Perovskite layers remain intact.

Absolutely. DJK Europe accompanies you from the initial testing phase in the lab to scaling up for industrial mass production and assists in the fine-tuning of the optical systems.
