Fabricación de rejillas de alto contraste para la División del espectro de dispersión de elementos en un Sistema de Concentración Fotovoltaica

The fabrication of high contrast gratings as the parallel spectrum splitting dispersive element in a concentrated photovoltaic system is demonstrated. Fabrication processes including nanoimprint lithography, TiO₂ sputtering and reactive ion etching are described. Reflectance measurement results are used to characterize the optical performance.
