Optical and Electrical Effects of p-type μc-SiO_x:H in Thin-Film Silicon Solar Cells on Various Front Textures

Figure 8

SEM images of front TCOs described in Table 2. Type A: HCl etched ZnO:Al with large craters, type B: HF and HCl etched ZnO:Al with small and steeper craters, type C: HCl and HF etched ZnO:Al with large and small crater features (double texture), and type D: Asahi type U SnO₂:F pyramid-like surface topography.
