Abstract

Meta-optics based on optically resonant all-dielectric structures is a rapidly developing research area driven by its potential applications for low-loss efficient metadevices. Halide perovskite metasurfaces are of particular interest for meta-optics, as they offer unique opportunities for the light control at subwavelength scale in real optoelectronic devices. In this report, we demonstrate suppression of reflection from MAPbBr3 perovskite layer from 25% down to a few percent level by it nanostructuring and, thus, optimization of its optical response. To achieve the strongest reflectivity suppression, we employ the so-called Kerker regime when electric and magnetic Mie resonances in each meta-atom are matched properly in a broad spectral range. Our results have a high potential for application in thin-film photovoltaics where reflection reduction plays a key role in device performance.
