methodnfor the efficient roll-to-roll laser structuring of electrodesnand functional layers on a solar module, characterizednthat in a continuous, highly productive and thermally gentlenRoll-to-roll process with a nanosecond laser pulse locally andnlayered material of the coated substrate,nwhich is coated with at least one functional layer, removednbecomes, so that parallel, from one another insulated conductor tracks andnSolar cells are created, whereby the high productivity therebynis achieved that the laser beam in parallel, focused lines overnthe entire width of the roll is fanned out and thenContinuity of the isolation trenches betweennthe solar cells by tuning the pulse rate to the belt speednis guaranteed by means of a synchronization unit. |
