Light Scattering and Current Enhancement for Microcrystalline Silicon Thin-Film Solar Cells on Aluminium-Induced Texture Glass Superstrates with Double Texture

Figure 1

AFM images of the three different superstrates used in this study. (a) Planar glass superstrate covered with nanotextured TCO (reference superstrate); (b, c) microtextured AIT glass superstrate covered with nanotextured TCO. The AIT superstrate in (b) has an intermediate autocorrelation length (mean feature size), while that in (c) has a large autocorrelation length.
