A common misconception is that alkaline textured silicon solar cell surfaces are characterised by features that are pyramidal and bounded by {111} planes. We analyse reflection distributions from various pyramidal textures, and find that features are probably hillocks, with an octagonal base and with base angle closer to 50–52° than the commonly accepted 54.74°. Analyses of antireflection, light trapping, photogeneration and recombination properties of textured surfaces should be reconsidered. Development of texturing processes resulting in higher base angles is encouraged.
