Figure 1From: Efficient PbS/CdS co-sensitized solar cells based on TiO2 nanorod arraysTypical FESEM images of the bare TiO 2 nanorod array and PbS-TiO 2 nanostructures. (a) FESEM image (40° tilted) of the bare TiO2 nanorod array grown on FTO glass by hydrothermal method. (b) FESEM images of PbS-TiO2 nanostructures after 1, (c) 3, and (d) 5 SILAR cycles.Back to article page
