We present a discrete implementation of generalized Harvey-Shack scalar scattering theory (gHS-SST) to calculate angular intensity distributions from height profiles of select randomly textured surfaces proposed for use in solar cells and covering a wide range of surface characteristics. We compare these calculations to high resolution angular intensity distribution measurements. These comparisons suggest that, the pupil function does benefit from an additional correction factor for rough surfaces containing lateral feature sizes on the order of the wavelength, which can be attributed to effective medium effects. Moreover, secondary interactions within the surface topography are shown to be a mechanism that partly redistributes scattered power, affecting angular intensity distribution results. These mechanisms emerge as the two main limitations of the gHS-SST in the far field, which nonetheless produce remarkable quantitative predictions.

广义Harvey-Shack理论在粗糙表面光散射中的实现

我们提出了一种广义的Harvey-Shack标量散射理论（gHS-SST）的离散实现，可以根据拟用于太阳能电池并涵盖广泛的表面特性的精选随机纹理表面的高度轮廓计算角强度分布。我们将这些计算与高分辨率角强度分布测量进行比较。这些比较表明，对于包含横向特征尺寸约为波长的粗糙表面，光瞳功能确实得益于附加的校正因子，这可以归因于有效的介质效应。此外，表面形貌内的二次相互作用显示为一种机制，可以部分重新分配散射功率，从而影响角度强度分布结果。
