Yoon Research Group (ECE, University of Utah)
Yoon Research group hosted K-12 students In Utah to discuss their ideas about solar technologies. Wow, they had many clever ideas! In addition to the PV discussion, the graduate students in Yoon’s group gave a demo on how to measure solar cell performance using a solar simulator. It was a fun time.
Dr. Yoon gave an invited talk at the MRS (Materials Research Society) Spring meeting. The title of her talk was “Fabrication of Characterization of PERC-Like CdTe Solar Cells” (link).
Our perovskite research in collaboration with U. Toledo (Prof. Yan’s group) and Los Alamos National Lab (Drs. A. Jones and M. Pettes) has been published in the Journal of Physical Chemistry-C.

Focused ion beam techniques have been frequently used to section metal-halide perovskites for microstructural investigations. However, the ion beams directly irradiating the sample surface may alter its properties far different from those of pristine, potentially leading to modified deterioration mechanisms under aging stressors.

Dr. Yoon presented the recent development of a wireless PV health monitoring system at the ECE Junior Seminar. This work has been primarily led by Aaron Coon (undergrad senior). Currently, we have a couple of openings for undergrad students. Please check out the information on the tap “Openings” (here).
We are excited about a new research project developing radiation-hard perovskite devices for medical systems and space applications. This work will be performed in collaboration with Prof. Connor Bischak (Chemistry), Prof. Glenn Sjoden (Nuclear Engineering), and Prof. Geoffrey Nelson (Radiation Oncology).

Etee gave a presentation of her research at the CTAC workshop. In this talk, she focused on her robust fabrication processes to define small contacts on individual grains. Understanding local transport near gran boundaries is critical in the development of higher-performance CdTe solar cells. CdTe PVs are one of the most promising solar technologies that meet the LCOE (levelized cost of energy) of the Department of Energy. (more information).
We congratulate Etee on passing her PhD candidacy exam. She has made excellent progress in developing high-efficiency CdTe-based solar cells by adapting unique nanofabrication approaches. Many congratulations! Well-done.
Dr. Yoon’s proposal has been selected for a new grant as part of the Cadmium Telluride Accelerator Consortium (CTAC). This project will be performed in close collaboration with the CATC research teams, including the National Renewable Research Laboratory (NREL), First Solar, the University of Toledo (PVIC), and many others. We are thrilled to work on this project.
Two EMC papers have been submitted by Etee and Ashif. Look forward to giving presentations at the Electronic Materials Conference (https://www.mrs.org/65th-emc).
Two PVSC manuscripts have been submitted.
