2023 08 Group Lunch

Anika and successfully completed their MATLAB program for a photovoltaic (PV) project. They developed a code that automatically extracts key solar cell parameters, such as short-circuit current, open-circuit voltage, fill factor, and efficiency. We express our gratitude for their exceptional work with us.

2023 06 Ashif gives a talk at the EMC.

Yoon Research Group gave two talks at the 65th EMC (Electronic Materials Conference; Santa Barbara, CA; link).

(1) “Photovoltaic Characteristics of PERC-Like CdTe Solar Cells” by E. Roy, K. Powell and H. Yoon.
(2) “Monitoring Stability of Metal-Halide Perovskites Under Combined Stressors of Ion-Beam and Heat” by A. Chowdhury, Y. Hsu, and H. Yoon.

 

Ashif gave an excellent presentation on his work on perovskite solar cells. He has investigated new technologies to measure the changes in the deterioration of meta-halide perovskites under environmental stressors.

2023 06 PVSC Presentation

We presented two research works at the PVSC (IEEE 50th Photovoltaic Specialists Conference).

(1) “Impact of Surface Roughness in Measuring Optoelectronic Characteristics of Thin-Film Solar Cells” by D. Magginetti, S. Jeon, Y. Yoon, A. Choudhury, A. Mamun, Y. Qian, J. Gerton, and H. Yoon (IEEE link)

(2) “Design and Fabrication of PERC-Like CdTe Solar Cells Using Micropatterned Al2O3 Layer” by E. Roy, K. Powell, C. Lee, G. Xiong, and H. Yoon (IEEE link)

 

 

2023 06 Welcome Hayden and Anika-

We welcome two SRI (Summer Research Intern) students, Ankia Mukherjee (Hillcrest High School, Junior) and Hayden Gardner (Jordan High School, Senior). We thank the College of Engineering at the University of Utah for organizing this program. Two students will work on programming on PV projects from June 12 to August 4.

2023 05 Graduation Lunch

We congratulate Aaron Coon (B.S.) and Josh Miraglia (M.S.) for earning their degrees. These two members performed excellent research work in Yoon’s group. While Josh is considering graduate school, Aaron has decided to work with Texas Instrument. We sincerely wish them the next step in their career path. Congratulations!!

2023 04 J. Phy. Chem. C (ion beam irradiation on PVSK)

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.
https://pubs.acs.org/doi/full/10.1021/acs.jpcc.2c09122#

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.
