Roll-to-Roll Nanotexturisation of Layers on Steel Foil Substrates for nip Silicon Solar Cells
2010
Light management is of utmost importance for thin film silicon solar cells. For nip cells, light management can be provided by textured back reflectors. In this paper, we demonstrate the fabrication of textured back contact foil on an industry compatible scale. A UV-curing lacquer on a stretch of 80 m of 30 cm wide steel foil was nanotextured in roll-to-roll mode, using the contact imprint method. Lab-scale samples were textured statically to test the effect on the growth of silicon by PECVD
