VON ARDENNE provides industrial equipment for vacuum coatings on materials such as glass, wafers, metal strip and polymer films. The major international manufacturers of crystalline and thin-film solar modules use our highly productive equipment for their production. We are also cooperating closely with them to develop the next generation of modules. VON ARDENNE acquired an excellent process know-how based on the more than 300 coating systems we have installed for crystalline solar cells and thin-film solar module providers. This expertise has been incorporated into the development of coating systems for the next generations of high-efficiency solar cells.

Our Supply Chain

Suppliers across the thin-film PV value chain form the backbone of the industry and have been key to technological advances and successes. From raw material production to providing manufacturing tools, equipment and balance of system (BOS) components, thin-film PV suppliers contribute to the continuous and automated production process and help drive down capital costs, increase throughput and improve module efficiencies and reliability.
