What made you decide to apply for a grant at the Leading House Asia?
From my undergraduate time up until now, I have participated in several photovoltaic conferences while majoring in materials engineering and applications in next-generation optoelectronic devices.
I was very interested in the presentation with outstanding photovoltaic stability engineering from Professor Michael Grätzel who has a global research influence. He gave a keynote speech at one conference I attended, and at the same time the yearly call for the bilateral exchange program between the National Research Foundation of Korea (NRF) and Switzerland was open. I applied for a grant with the goal of expanding my academic and research experience.

How did you secure a host professor?
Initially, I sought out experts in my field of study, leading me to discover Professor Michael Grätzel at Switzerland's EPFL.
Aware of Professor Grätzel's story of presenting at a solar cell conference in Korea, I reached out to him to network and express my research interests and goals. I communicated my aspiration and keen interest to study from Professor Grätzel's research group and contribute to his research group.Thanks to his delicate review, Professor Grätzel granted me the opportunity to participate in an exchange program, allowing me to conduct further research within his group at EPFL/LPI.

How would you describe your experience of the programme?
Becoming a member of Professor Grätzel's group offered an astonishing experience in my research life, providing me with unique insights and opportunities. I participated in regular research seminars with not only the group's experts but also with excellent speakers from outside the group, which allowed me to discuss and learn about various aspects of perovskite photovoltaic engineering.
Through these discussions and learning opportunities, I gradually came to understand the most advanced research techniques and methodologies in the field. Thanks to the multi-faceted perspectives and experimental experiences, I gained the wisdom to adapt to new environments, which will prove invaluable in my future research endeavors. The benefit of working alongside talented researchers and benefiting from their expertise and guidance was a significant highlight of the program.

What role did the Leading House Asia play in the programme?
The Leading House Asia played a pivotal role in establishing a connection between the host institution (EPFL/LPI) and myself, as a research fellow. They facilitated the initial communication and nurtured the relationship, ensuring a smooth transition into the new research environment.
The support from Leading House Asia was not limited to just making connections. They provided substantial financial support, which was crucial for my stay and research activities in Switzerland. Also, they handled all necessary documentation, enabling me to focus on my research.
Leading House Asia's role did not end with the conclusion of the exchange program. They provided post-program care, ensuring that I was able to reflect on and leverage the experiences and knowledge gained during the exchange. This included follow-up opportunity, where I could discuss my experiences and how they could be applied to my future research endeavors.

What were the impacts you made through the project/partners/individual?
I think my research project, focusing on "Engineering for Integrated 2 in 1 Perovskite Optoelectronics," could bring significant contributions to the field of perovskite optoelectronics because the research outcome demonstrated the potential for hybrid applications (photovoltaics and photodetectors) and performance enhancements of perovskite optoelectronic devices. Consequently, an article detailing these results is currently being prepared for submission to the SCI journal by Professor Grätzel’s institute and my own.

The project's findings have the potential to impact commercial industries. By leveraging the high light energy detection properties of perovskite, the development of customized indoor and outdoor applications becomes possible. It will open up new avenues for commercial applications and product development.

Testimonial: what were your personal experiences/thoughts on the bilateral cooperation experience?
Participating in the bilateral cooperation experience was an enriching and inspiring opportunity for me. Visiting the Swiss Convention Center and witnessing the innovative dye-sensitized solar cell (PV) win-dow project led by Professor Grätzel was a highlight. Taking a group photo with the EPFL/LPI team was a memorable moment, and it deepened my understanding of real-world applications of our research.
The bilateral cooperation experience not only provided valuable networking opportunities but also laid the foundation for potential future collaborations. It emphasized the importance of continuous scientific cooperation and the exchange of ideas. This experience reinforced my belief in the significance of international research cooperation in addressing global challenges and advancing our field. The chance to learn from top experts and contribute to impactful projects was truly invaluable.
