One-step module production
3D-Micromac launches the first production equipment worldwide, which can conduct the integrated series-connection of a thin-film solar module on one single platform and in one single production step. The new One-Stop-Patterning process (OSP) only structures the modules once all of the functional layers have been deposited on the substrate. This significantly simplifies the production process. Formerly, thin-film modules were structured with a laser or a mechanical unit after each individual layering step, which required expensive cleaning steps, lengthened processing times, and led to efficiency losses. The OSP process minimizes dead zones to less than 100 micrometres, simplifying manufacturing and increasing efficiency. In addition, the new process prevents inaccuracies, which are caused when the substrate is positioned and aligned on different tables—an improvement that increases the efficiency of a thin-film module by up to 0.8%.
