Single-layer coating design and pyramid texture estimate

Idealised optics: constant refractive indices, lossless film, normal incidence, unpolarised light. Defaults are the page's illustrative values (silicon 3.5, air 1.0, design wavelength 600 nm). Results are not measured data for any cell or glass.
