Magna Cum Laude

Minkyung is interested in developing novel solar cell materials with high efficiencies by combining knowledge and techniques from various domains such as geosciences, materials science, chemistry, data science and computer science. To solve the instability problems of 3D halide perovskite solar cell materials, she studies achieving metastability by applying high pressure to the system via experiments and simulations. She utilizes various machine learning models to predict material properties from pressure/strain-tuned structures and identifies leading structural desecriptors that can better represent the system. Her research goal is to design next-generation high-performing photovoltaic materials with unique properties that contribute to environmental sustainability.

She is currently studying the behavior of 3D halide perovskites that include all-inorganic and hybrid organic-inorganic perovskites under high pressure using Diamond Anvil Cell (DAC), X-ray Diffraction (XRD), Density Functional Theory (DFT) calculation, and various machine learning techniques. 

She mainly researched the electronic properties of thermoelectric materials using DFT calculation during her master's study. In particular, she focused on developing a numerical model to evaluate electron-defect scattering phenomena induced by copper vacancies in bismuth copper oxysulfide supercells. Also, she estimated the effect of vacancy formation on the performance of thermoelectric sulfides using BoltzTraP.

She enjoys hiking, camping, reading, playing piano, and watching movies in her free time.
