Understanding Effect of Ion Migration Through Correlating Chemical and Ionic Properties in Halide Perovskites

Energy icon, disabled. An orange lightning bolt.

Perovskite Solar Cells (PSC) are a very promising area of study because of their superior optoelectronic properties, affordability and reduced carbon footprint of manufacturing compared to other solar cells. The drawback of PSCs is the fast degradation process under heat, light and/or moisture. Ion movement is one of the main causes of the degradation process. In this research project, ion migration in PSCs is quantified by using Glow Discharge Optical Emission Spectroscopy (GD-OES) to show elemental distribution in the PSC after exposure to heat and light. How ionic properties influence degradation is the ultimate goal of this work.
