PhD thesis: TBC

My area of interest lies in semiconductor-based devices, where broad real-world applications intersect with the theoretical complexities of band structures and interface phenomena. More specifically, research on ultra-thin-film photovoltaics (PV) benefits both my short-term academic pursuits and long-term entrepreneurial goals. These technologies hold great promise for next-generation space power systems and emerging terrestrial applications, such as the integration of solar cells into electric vehicles.

During this PhD program, I aim to optimize the efficiency of ultra-thin PV by addressing the light-management challenges intrinsic to these structures. I plan to achieve this through two primary approaches: incorporating novel photonic and plasmonic structures to optimize light confinement within the device and conducting exhaustive characterizations of the fabricated samples. This will be followed by modelling to gain a theoretical understanding of the precise optical environment and recombination processes that currently limit performance.

Who or what inspired you to pursue your research interests?

I have always been driven by my passion for both the theoretical beauty and the practical applicability of physics. The idea of delivering innovative solutions and advancements for human society using scientific knowledge deeply motivates me. In this sense, research in ultra-thin photovoltaics perfectly aligns with my scientific aspirations. These technologies create flexible, efficient, and low-mass power sources, paving the way for long-term space explorations and green transportation.

Moreover, the problem-solving skills and technical training gained in the semiconductor industry are desirable for my long-term career goals, as I aspire to establish a start-up company that can translate my scientific endeavors into impactful technologies for the benefit of society.
