We are engaged in the process development of roll-to-roll processes, focussing on homogeneity and overcoming challenges for industrial upscaling. Thin-film technology makes it possible to deposit solar cells on foils (e.g. steel or polyimide) . in this area, we have been cooperating with the company Sunplugged for over 10 years. Particularly in the production of polycrystalline, multi-component absorber layers using the roll-to-roll process, there are complex correlations between machine parameters and the resulting layer properties or the performance of the solar cells.
