Applications of Laser Micromachining in Photovoltaic Processing

Driven by ecological awareness and short-running fossil combustibles, photovoltaics is gaining ever increasing importance for the production of energy. Moreover, extensive government aids formidably abet solar industry both on the national and the international level.

In order to achieve a reduction of manufacturing costs and increase the efficiency in parallel, manufacturers of solar cells readily invest in fully automated state-of-the-art production lines. In such fabs, the utilization of lasers guarantees high efficiency and throughput at best attainable precision and minor damage to the cells.

Particular advantages of laser machining of fragile silicon wafers consists in contactless energy insertion, the capability of flexible beam guidance, and the exact control over supply of energy. Damage to the material is avoided that way as well as failure rates are minimised.

3D-Micromac AG provides powerful and highly precise stand-alone systems as well as integrated solutions for existing, fully automated production lines for laser machining of solar cells. Numerous process monitoring methods including tracking and tracing of process parameters and online energy monitoring ensure additional process reliability. In parallel, we are ready to develop new processes or systems on customer’s demands as a qualified partner.
