Abstract

Dielectric metamaterials with high refractive indices may have an incredible capability to manipulate the phase, amplitude, and polarization of the incident light. Combining the high refractive index and the excellent electrical characteristics of the hybrid organicinorganic perovskites (HOIPs), we demonstrate that metamaterial made of HOIPs can trap visible light and realize effective photonto-electron conversion. The HOIP metamaterials are fabricated by focused ion beam milling on a solution-grown single-crystalline HOIP film. The optical absorption is significantly enhanced at the visible regime compared to that of the flat HOIP film, which originates from the excited Mie resonances and transverse cavity modes with inhibited interface reflection. Our results point to the potential application of HOIP metamaterials for high-efficiency light trapping and photon-to-electron conversion.
