Abstract: My research focuses on the performance enhancement of photovoltaics, such as silicon solar cells, organic solar cells, and perovskite solar cells. Power conversion efficiency, stability, and flexibility can be improved by employing carbon allotropes. Comprising of carbon atoms only, the carbon allotropes, namely carbon nanotube, graphene, and fullerene, exhibit various properties depending on their electronic configurations, ranging from conductors to semiconductors. Their earth-abundance and resilient nature mean that they are perfect replacements for the conventional materials, which are finite and inflexible. Thus far, I have applied a wide range of modified carbon allotropes to solar cells to offer solutions to their intrinsic problems. In this talk, I will mainly focus on single-walled carbon nanotubes as next-generation electrodes and Li-containing endohedral metallofullerene as both a dopant and an anti-oxidant, introducing the frontier carbon allotropes technology and how they are making an impact to the field of solar cells.
Biography: Il Jeon read chemistry
for both undergraduate and postgraduate at the University of Oxford, UK in
2008. Upon graduation, he worked in LG Display Co. Ltd., South Korea for 5
years as the youngest senior researcher, developing optical films, OLED, and quantum
displays. In 2016, he received a Ph.D. degree in chemistry with honours at the
University of Tokyo, Japan. Having worked as a JSPS postdoctoral fellow and an
assistant professor, he is now a lecturer (senior assistant professor) at the
same university. His research focuses on the development of low-dimensional materials
and their optoelectronic applications.
