All existing thin-film PV technologies, especially the Cu(In,Ga)Se-2 (CIGS)
-based technology, have a high cost reduction potential at high production
volumes. The challenge for the future is to combine high production volumes
with high throughput, sufficient yield and superior quality. ZSW has devel
oped in-line processes for all deposition steps for CIGS modules. In severa
l batches average efficiencies of above 11% and a maximum of 12.7% have bee
n achieved. For the next scaling up step Wurth Solar GmbH & Co. KG, a joint
venture of ZSW, Wurth group, and EnBW AG, a German utility, was founded to
commercialise CIGS technology. (C) 2001 Elsevier Science B.V. All rights r
