Scratcher for Thin Film Solar Cells

Scratcher device which was designed for the Group for Thin Film Physics at the ETH Zürich. The group was developing a novel, flexible solar cells. The solar cells were made of thin films of Mo, CIGS (Cu, In, Ga, Se2) and ZnO. For research purposes these films were manufactured in vacuum chambers on glass plates. The scratcher was meant to structure the film on the glass plate into individual cells.
