| Abstract Scope |
If a thin layer is sputtered or vapor-deposited onto a transparent PET film, and this is then brought into contact with a product surface, then this PVD layer can be transferred using a standard marking laser. In addition to the possibility of selectively coating products, the PVD layers can also be specifically functionalized during the laser-induced layer transfer - in such a way that they are permanently catalytically active, for example, or have properties that previously only occur in free nanoparticles. Results from XRD and SEM analyzes are presented, as well as profilometric images of "lasered", highly porous and dimensionally stable silicon layers, which illustrate how the morphology and topography of the silicon layers can be specifically adjusted and specific functionalities can thus be implemented . Finally, specific possible applications are presented from the areas of solar technology (thin-film modules) and battery cell development (silicon-air battery). |
