Fig. 2From: Improved Metal Oxide Electrode for CIGS Solar Cells: The Application of an AgOX Wetting LayerComparison of the sheet resistance measured of OMO electrodes of the CIGS solar cells with different thicknesses of the intermediate metal. Samples without (black) and with (red) wetting layers are shown. The dashed lines represent the sheet resistance of OMOs with constant resistivity, as would be expected without a change in morphology of the Ag layerBack to article page
