In order for the commercial production of large CIGS modules on the multi-MW scale to be successful, the processes must still be streamlined and optimised taking considering both economical and ecological aspects. This project aims to support the developme nt of this material- and energy-saving thin-film technology so it can gain a foothold in the free PV market. Promising laboratory results will be transferred to large-scale production, where the availability of appropriate production equipment and very hig h material and process yields are of decisive importance. 4 universities, 2 research institutes, and 4 companies will work closely together in order to merge the physical understanding of the processes and the engineering know-how, which are necessary for up-scaling the CIGS technology to a marketable multi-megawatt production volume. We will focus on: (1) very high-quality modules manufactured by coevaporation of CIGS and applying cost-effective methods, ETA up to 14 % on 0.7 m2; (2) the development of Cd-free buffer layers for Cd-free CIGS modules on an area of up to 0.7 m2, ETA up to 12 %; (3) and the development of a mid-term alternative: electrodeposition of low-cost CIS modules with ETA above 10 % (estimated cost about 0.8 E/Wp). We will transfer the Mo back contact sputtering know-how to a specialised European large-area glass coater to provide substrates for both the coevaporation and the electrodeposition approaches. All process developments such as modifications of the back contact, wet- or vacuum-deposited buffer layers, the multi-stage coevaporation of CIGS, or improved Ga incorporation in electrodeposited absorbers will first be tested and evaluated on the laboratory scale. Successful approaches will be up-scaled and transferred to three independ ent commercial CIGS pilot lines located in three different European countries. Novel process and quality control techniques must also be developed and applied to reach these ambitious goals.
