Synthesis of ZnO Nanowires and Their Photovoltaic Application: ZnO Nanowires/AgGaSe₂ Thin Film Core-Shell Solar Cell

Figure 3

Top-view SEM images of ZnO nanowires synthesized on ZnO seed layers (on soda-lime glass substrates (SLG)) deposited by (a) sol-gel and (b) sputtering techniques. Inset figure shown in part (a) presents the AFM image recorded for ZnO seed layer on SLG substrate deposited by sol-gel route.
