Embossed Mie resonator arrays composed of compacted TiO₂ nanoparticles for broadband anti-reflection in solar cells.

ABSTRACT: Mie resonator arrays formed by embossing titanium dioxide (TiO₂) nanoparticles (NPs) from solution are investigated as optical coatings for anti-reflection applications. Compacted nanoparticle assemblies offer unique possibilities to tailor the effective refractive index (RI). Here, we demonstrate a simple table-top, low pressure, and low temperature method to fabricate structured optical coatings. TiO₂ nanostructures in the form of nanodisks support Mie resonances in the visible wavelength spectrum and exhibit strong forward scattering into the high index substrates, making them suitable as broadband anti-reflection coatings for solar cells. TiO₂ NP-based nanodisk arrays are designed, fabricated, and characterized regarding their anti-reflection properties
