Abstract Text All inorganic cesium lead halide perovskite nanocrystals with composition CsPbX3 (X= Cl-1, Br-1, or I-1) have gained considerable attention due to their outstanding photophysical properties which make them major candidates for use in Luminescent Solar Concentrators (LSCs) for light harvesting applications. LSCs make use of fluorophores such as organic dyes or quantum dots to waveguide incoming light towards a photovoltaic (PV) cell by means of absorption and reemission. While a conventional LSC achieves light trapping through total internal reflection, our proposed structure utilizes aligned dipole-emitting nanorods to concentrate incoming light towards the PV. CsPbX3 nanorods were synthesized through the water-triggered transformation of nanocrystals and aligned using an A/C electric field. Based on preliminary theoretical studies, we believe that perovskite nanorods would be an ideal material for solar concentration.

Role: I synthesized all-inorganic Cesium Lead Halide perovskite nanocrystals and used a water-triggered transformation to grow them into nanorods. I characterized these samples by measuring their photoluminescence and absorbance, and eventually aligned them using an A/C electric field.
