title: Silicon films as selective absorbers for solar energy conversion.
abstract: The optical constants below the fundamental absorption edge (up to 5 microm) of silicon single crystals and sputtered amorphous silicon films at high temperatures (up to 800 degrees C) have been determined and the photothermal efficiencies of silicon-metal selective absorbers for thermal solar energy conversion calculated.
