High Density Surface Nanotextures for Broadband, Omnidirectional Antireflection
Brookhaven National Laboratory, New York, United States
The inventors have developed a broadband, omnidirectional antireflective surface nanotexture comprising high density, close-packed arrays of nanocones / nanopillars that taper from a base, such as a bulk silicon substrate, to an extremely narrow top edge, creating a tapered interface between the air and the bulk base material.
Primary Application Area: Renewable & Hydrogen Energy

Value Proposition: The nanoscale feature size of these structures may be ideal for the production of thin film based solar cells, possibly reducing the amount of active material needed. Fabrication is amenable to low-cost, large area manufacturing. The refractive index profile may be controlled through the geometry of the etched surface.
