Kate Higgins works in a lab.

What is your thesis topic?
Utilization of automated synthesis and machine learning for the exploration of hybrid organic-inorganic perovskite combinatorial libraries.

How is materials processing involved in your research?
To create combinatorial libraries of various hybrid organic-inorganic perovskite systems, I utilize a pipetting robot, commonly used in the biological field, to make microcrystals. This requires taking into consideration certain aspects, such as solvents, antisolvents, and fabrication methods.

Provide an example of where the material, process, or properties you are studying might find an application.
Hybrid organic-inorganic perovskites have emerged as a promising candidate for solar cell applications. However, the stability of these materials under illumination and in ambient conditions remains elusive. In this project, I am first determining the optimal compositions for this application based on their optoelectronic properties. Further, I am developing a method to measure the change in these optoelectronic properties over time in ambient conditions. From this, I will be able to determine which hybrid organic-inorganic perovskites have the best intrinsic stability.
