Light scattering inorganic substrates having an inorganic sheet having composite features distributed on a surface of the inorganic sheet, wherein the composite features each have at least a first and a second size scale. The first size scale enhances light absorption at wavelengths in the range of from 350 nm to 600 nm, and the second size scale enhances light absorption at wavelengths in the range of from 600 nm to 1100 nm. The substrates are, useful, for example, for photovoltaic devices.
