May anyone help me with the absorption coefficient graph for sapphire in the visible range (i.e. between 200 nm to 1000 nm)?

The values are required for the simulations of InGaN/GaN based devices designed over sapphire substrate.

Is it possible to grow thin films over photonic crystal based solar cells, with PhC of 1by 4um having thickness 1.3 um.?

As the dimensions are in almost nanometers, is it technically feasible to design such a structure and then characterize and check the electrical output of such a structure?
