Measured and calculated reflectance spectra using FDTD with the texturized interface model and the anionic layer model. a d _int = 100 nm and b d _int = 440 nm. The red dots represent the measured reflectance spectra, the green dashed line the FDTD result for the texturized interface model and the blue solid line represents the FDTD result for the anionic layer model without absorption
