Hybrid halide perovskites have become a prodigy for emerging semiconductor materials, driven mainly by their success as high-performance photovoltaics, with CH3NH3PbI3 leading the way and competing with state-of-the-art Si, CdTe or CIGS solar cells. As a result, three-dimensional hybrid halide perovskites have been studied intensely from a fundamental point of view as well as for photovoltaic and photonic applications.
My research focuses on the next generation of hybrid halide perovskites, specifically, two-dimensional hybrid halide double perovskites based on non-toxic metals like silver and bismuth. The variety of modulation through organic cations, inorganic layers and different morphologies of crystals and thin films offers intriguing optical and physical properties.
