Fourier light scattering model for treating textures deeper than the wavelength.
F. -J. Haug, M. Bräuninger, C. Ballif


Abstract
We apply a Fourier-scattering model to describe light scattering in solar cells with textured surfaces. For the size and inclination angle of typical micro-textures, scattering may occur into large angles. This makes the model prone to paraxial errors. We present a non-paraxial formulation and discuss the transition from the domain of refraction at large facets to scattering at small features.
