Realization of Colored Multicrystalline Silicon Solar Cells with SiO₂/SiN_x:H Double Layer Antireflection Coatings

Figure 2

Calculated perceived color and short-circuit current density as a function of the thickness of (a) the standard single layer SiN_𝑥:H (with 𝑛=2.1 at 633 nm) on a concave-like textured solar cell and (b) SiO₂ on top of the standard SiN_𝑥:H (𝑛=2.1 at 633 nm, and thickness = 80 nm).
