ABSTRACT:
The invention contemplates a highly solar-energy absorbing device wherein the surface exposed to incident solar energy is a particularly characterized roughness of an amorphous semiconductor material, the particular characterization being that of an array of outwardly projecting structural elements of relatively high aspect ratio and at effective lateral spacings which are or include those in the order of magnitude of wavelengths within the solar-energy spectrum.
