Abstract

We report the fabrication and characterization of TiO ₂ sol-gel diffraction gratings on silicon substrates by using nanoimprint lithography. The gratings are homogeneous and free of defects and cover an area of 25cm ². Minority carrier lifetimes of up to 900μs for imprinted samples under illumination are reported, which Kelvin probe measurements indicate is due to light-generated negative charge in the films. The structures reported here are very promising as light-trapping, passivating coatings for solar cells.
