Abstract

In this work we discuss the design, fabrication, and characterization of hyperbolic metamaterials (HMMs) based on plasmonic metals and solution processable perovskites. The optical properties of the HMMs are characterized using spectroscopic anisotropic ellipsometry, angle resolved reflectometry and compared with the theoretical/simulated results derived from the effective medium approximation (EMA) approach. Furthermore, the impact of replacing the outer layer on the homogenization of the composite is studied by monitoring the evolution of ψ and Δ of the HMMs in each fabrication step. The HMMs presented here exhibite epsilon near zero (ENZ) and epsilon near pole (ENP) near 550 nm. Finally, we show how this material can be used for effective light concentration in the field of perovskite solar cells exploiting the unusual optical constants near the ENZ/ENP regions.
