StarDisc

The q-switched StarDisc offers not merely high power in the fundamental mode TEM₀₀ but also an ideal range of pulse widths. The combination of high pulse peak power and material-adjusted pulse duration provides for outstandingly short process times for various applications.

Application Example Rear Contact Solar Cells

For plating through front sides of solar cells, several 10,000 holes with a diameter of approx. 30 µm are drilled into a cell in a grid pattern and filled with conductive material. The StarDisc achieves extremely short processing times per one solar cell of 5-10 seconds . Ideal precondition for an inline integration of plating through procedures into the production process.

Like all lasers made by ROFIN, the StarDisc is based on a platform technology and relies on a consequent modular concept. The user benefits substantially fromMaking use of industry-proven standard components brings substantial benefits to the customers like lower investment costs, less maintenance and higher reliability.
