Figure 1From: Hydrothermal Growth and Application of ZnO Nanowire Films with ZnO and TiO2Buffer Layers in Dye-Sensitized Solar CellsSEM images of ZnO nanowire arrays grown on FTO substrates with different ZnO seed obtained from (a–f) the spin-coating method, (g–k) the dip-coating method.a,c,e,g,i andk correspond to top-view observations,b,d,f,h,j andl correspond to cross-sectional views. The insets show high-magnification SEM imagesBack to article page
