Yoon Research Group (ECE, University of Utah)
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.
Yu-Lin and Ashif’s manuscript has been submitted for a journal publication. This paper describes the impact of the Ar-ion beam on the subsurface of metal-halide perovskites.
We are grateful to have talented group members who are also generous and kind in helping each other. We look forward to seeing the growth of our team next year. (left to clockwise: Etee, Dr. Yoon, Josh, Ashif, Ashraful, and Aaron)
Our recent results on CdTe solar cells (group-V, Cu-doped CST absorbers) were shared at the 6th CdTe workshop. Etee Kawna Roy primarily leads this work. The microcontact approach complements diverse group efforts in the CTAC (Cadmium Telluride Accelerator Consortium; https://www.usa-cdte.org/). We thank our collaborator (First Solar, NREL) for sharing the high-quality CdTe samples.
Dr. Yoon and her group’s stories have been shared in the College of Engineering (COE) annual report (here). This article focuses on the projects of solar cells.
We strive to utilize solar energy to meet the rapidly-growing social demands for energy. Our research builds on the fundamental understanding of photocarrier transport at the nano/microscale. We are expanding our efforts to terrestrial and space PV applications.
