Revolutionizing
Solar Cell Manufacturing
Solar energy is a key component of the global energy transition: Photovoltaic systems efficiently convert sunlight into electrical energy and thus enable sustainable, decentralized power generation. Whether for rooftops, open spaces, or integrated applications—solar technologies are highly versatile and constantly evolving.
The cost-effective production of high-performance solar cells places high demands on precision, throughput, and process stability. This is exactly where our ASYS Energy Solar solutions come in. We develop and integrate customized production systems for the manufacture of solar cells: from material feeding through coating, soldering, and lamination processes to testing and handling solutions — Innovation “Made in Germany”.
ASYS Energy Solar is developing the next generation of solar cell metallization systems—designed to increase throughput beyond today’s limits. Thus enabling manufacturers to achieve future production goals today without compromising on stability, reliability, or industrial compatibility.
XH6 – Next Generation Screen Printing Solution
The next‑generation ASYS screen printing solution is designed to meet the increasing demands of ultra‑fine line metallization and high‑throughput solar cell production. By integrating multiple process steps into a single platform, the system combines patented parallel alignment procedures with vacuum‑based transport. This enables precise cell‑to‑cell positioning, minimized process variation, and stable, industrial‑scale performance for advanced solar cell technologies.
Incoming solar cells are loaded into a defined cell matrix and aligned using ASYS’ patented parallel alignment procedure. Cell positions are measured with high precision, while offsets between the cell matrix and the vacuum gripper are detected in parallel. This approach ensures fast alignment cycles, reduced cycle time, and accurate initial positioning as the foundation for ultra‑fine line printing.
The aligned cell matrix is transferred using an in‑vacuum transport system that maintains precise cell‑to‑cell alignment throughout the process. During transport, offsets between the vacuum gripper and the vacuum band are measured and compensated.
This ensures positional stability with an accuracy of 2–4 μm, eliminating cumulative alignment errors and preserving matrix integrity at high throughput.Before screen printing, the system measures the offset between the vacuum band and the screen. All detected offsets from previous steps are corrected within a single alignment procedure, enabling precise registration between cells and the printing screen. This integrated correction concept ensures consistent fine‑line printing accuracy, reduced variation, and reliable metallization quality at industrial production speeds.
Key Advantages of
the ASYS Solution
ASYS metallization solutions improve performance and efficiency through an optimized line concept with fewer manual operations, reduced operator demand, and fewer parallel lines. Integrated processes minimize downtime, energy‑efficient machines lower power consumption, and the compact layout reduces footprint. In a 5‑GW comparison, ASYS achieves the same output with only four lines instead of eight in conventional solutions.
- - 75% reduced downtime for screen exchanges
- - 40% reduced number of operators
- - 20% reduced operating power
Savings of 3–4 Mio.$ of OPEX per year
