The optical constants below the fundamental absorption edge (up to 5 μm) of silicon single crystals and sputtered amorphous silicon films at high temperatures (up to 800°C) have been determined and the photothermal efficiencies of silicon–metal selective absorbers for thermal solar energy conversion calculated.
