Ilia Pavlovetc is a fifth-year graduate student advised by Prof. Masaru (Ken) Kuno in the Department of Chemistry and Biochemistry. He presented "Suppressing Cation Migration in Hybrid Perovskites" at the ND Energy PD&GS Seminar in October 2020.

Pavlovetc’s research focuses on hybrid perovskites, important materials for third-generation (low cost/high efficiency) solar cells. Specifically, he is developing and applying novel approaches of optical microscopy for characterization of new semiconductor materials and optoelectronic devices.

“Better understanding of their optoelectronic performance will bring their commercialization a step closer,” Pavlovetc said.

In addition to his work in the Kuno lab, Pavlovetc has collaborated extensively with researchers on and off campus. He developed a new approach for super-resolution infrared imaging with ND Energy faculty affiliate Gregory Hartland, professor of chemistry and biochemistry.

Pavlovetc also works with a team at the National Renewable Energy Laboratory (NREL). Led by Joey Luther, senior scientist at NREL, the group has helped to prepare and conduct stability testing of solar cell devices.

Like many of ND Energy’s associated researchers, Pavlovetc has made great use of the Materials Characterization Facility (MCF). He works mostly with the ATR-FTIR and UV-Vis.

“While these instruments are quite basic, the information they provide is invaluable,” Pavlovetc said, noting that the MCF provides easy access to a number of materials characterization techniques.

After receiving his undergraduate degree in physics from IMTO University in Russia, Pavlovetc spent a few years working as an engineer before he arrived at Notre Dame in 2016. His primary interest in this field of research was to apply his knowledge of optics and physics to physical chemistry problems.

In 2020, Pavlovetc received the Forgash Graduate Fellowship for Solar Energy Research. Support from this fellowship has allowed him to present his findings at a number of national conferences. He has received additional funding for conferences from the Department of Chemistry and Biochemistry, The Graduate School, and the Graduate Student Union.

Pavlovetc believes it’s important for the general public to appreciate the amount of research that is necessary to produce the devices we use.

“Understanding of the research flow by the general public will possibly bring more attention to the basic research,” he said. “As a consequence, it might bring more money and people to research professions.”
