Antireflective surfaces by Nanosphere Lithography

Date:
2007-
Themes:
Nanophotonics and Biomimetics, Nanoelectronics

Inspired by nature's highly - evolved technique of producing antireflection in the eyes and wings of some species of moth, densely-packed pillars with heights and spacings of approximately 200 nm are created for use in solar cells. The effective refractive index gratings that are produced allow for broad range of wavelengths and angles of incidence to be antireflected efficiently. We are investigating ways to produce high quality antireflection layers on silicon using nanosphere lithography, a cheap, large-area and massively parallel self-assembly method.
