Abstract

Surface texturing plays an important role in trapping light in photovoltaic materials. Understanding and modeling diffuse scatter from various textured silicon surfaces should aid in increasing light trapping in these materials, as well as improving material characterization and inspection during manufacture. We have performed Mueller matrix bidirectional reflectance distribution function (BRDF) measurements from a variety of textured silicon surfaces. Simulations, using multiple reflection polarization ray tracing, reproduce many of the features in the data. Evidence for diffraction, however, can also be observed, suggesting that a purely ray-tracing approach is insufficient for accurately describing the scatter from these materials.
