Haug, F. -J.Brauninger, M.Ballif, C.2017-05-012017-05-01201710.1364/Oe.25.000A14https://infoscience.epfl.ch/handle/20.500.14299/136927WOS:000397317400002We 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.
