Within the context of a customer order regarding the rear-side contacting of emitter wrap-through (EWT) solar cells, the Chemnitz-based 3D-Micromac AG successfully positioned the microDRILL-EWT laser micro-processing system, enabling the efficient and, at the same time, high-precision fabrication of micro holes in crystalline solar cells, on the market. In order to attain the high level of precision required in laser processing, the wafers are aligned using camera technology.

The father of the Germanic gods, Wotan, was not just a man of battle and prodigious consumer of mead, he was also a man who used the sky’s light. As the god of thunder and lightning, he took light and used it in a specific way. This is the tradition now being followed by the JENOPTIK-VOTAN^TM Solas range of machines. The latest laser technology, high-end mechatronics and sophisticated vision technology are combining to take a new route towards improved energy generation.
