Abstract
The invention relates to a method for structuring transparent, conductive layers, especially for structuring transparent electrode layers in thin-layer components. The selected wavelength (&lgr;) of the laser used for structuring should fall substantially within the plasma absorption range of the transparent electrode layer and should fulfill following three requirements: a) the wavelength &lgr; of the laser must be greater than the cut-off wavelength &lgr; for optical absorption in the base absorber, b) the wavelength &lgr; of the laser must be greater than the cut-off wavelength for free substrate absorption (plasma absorption) &lgr; in the transparent electrode layer, and c) the wavelength &lgr; of the laser must be less than the cut-off wavelength for metallic reflection &lgr; on the transparent front electrode.
