TALKING POINT Arvid Müller Headquarters in Dresden. Taking wafer coating to a new level VON ARDENNE develops and manufactures advanced The company owes its name to Manfred von Ardenne, a highly gifted, visionary vacuum coating equipment for the deposition of ultra-thin and dedicated scientist and inventor born in 1907. His contribution to inventions such functional layers on materials such as glass, metal strip, as the radio receiver, the television, and wafers and polymer films. In this article, we take an exclusive the scanning electron microscope is extraordinary. He held approximately 600 look at the company and its latest product, XEA|nova. patents in radio and television technology, electron microscopy, nuclear plasma, and medical technologies and was the author The German family-owned company of countless books and publications – VON ARDENNE’s key technologies are without holding a degree or even a high magnetron sputtering and electron beam school diploma. It was thanks to his evaporation and it holds more than 750 farsightedness and hard work that he became such a famous scientist. patents worldwide. Today, VON ARDENNE focuses on The company was founded in 1991 as a reliable technologies to deposit thin layers spin-off of the former Manfred von Ardenne on large areas and very large substrates Research Institute in Dresden, Germany.

In the last years, the market for energy generation, energy saving and lately also the energy storage industry strengthened ARDENNE VON and broadened its technology portfolio. At the recent solar exhibition Intersolar Europe 2014 in Munich, VON ARDENNE introduced its latest vacuum wafer coating platform: the XEA|nova. Wafer based photovoltaics has been the workhorse in solar energy generation for years. At this exhibition, however, we saw the latest ultra-thin, highly efficient crystalline solar cell designs. As a leading developer and manufacturer of vacuum coating equipment for the PV industry, VON ARDENNE has incorporated its superior know-how into a new modular platform, especially designed for these products. The necessary know-how has been gained from over 100 industry proven photovoltaic systems.
