Electronic, Excitonic and Polaritonic Properties of Hybrid Metal-Halide Perovskites

The electronic, excitonic and polaritonic properties of hybrid metal-halide perovskites were investigated using multiple spectroscopic techniques. Herein, we compare charge-carrier interactions in two different hybrid perovskites that have strong potential for use in solar cells. Further, we fabricate and investigate perovskite-based systems that are cost-effective, easy-to-make and readily scalable. These systems allow charge-carriers to flow without resistance through the quantum interaction of light and matter - and are a promising platform for electronic circuits that do not heat up when used - reducing global greenhouse emissions. This is the first instance of this phenomenon in a readily-scalable system.
