For the automated loading and unloading of a workpiece carrier with differently sized wafers prior to PECVD coating, acp systems developed an image-processing-based robotics solution for a leading manufacturer of space solar technology.

The flat vacuum gripping system, which is quickly interchangeable for the differently sized wafers, consistently maintains the specified positioning accuracy of ± 0.1 millimeters when loading the workpiece carriers.(Image: Azur Space Solar Power)

The Heilbronn-based (Germany) company Azur Space Solar Power GmbH is one of the world's leading companies in the development and production of highly efficient multi-junction solar cells for space and terrestrial concentrator systems (CPV). The solar cells are based on the latest triple- and quadruple-junction technology, where the layers are built on a germanium substrate.
