As a PhD student in Physics, I am currently working on device physics within material science. Scientific development is becoming increasingly specialized, with many researchers focusing on deeply exploring particular niches. At the same time, scientific problems are becoming more complex, making interdisciplinary solutions inevitable. As a young researcher in the community, I would like to know how to strike a balance between the depth and the breadth of the topics we are working on, and how we should develop ourselves in the future to cope with the rapid development of scientific progression.

My research centers on the development of stable, efficient, and environmentally sustainable tin-based perovskite solar cells. As a promising alternative to lead-based perovskites, tin halide materials offer lower toxicity but suffer from significant challenges in surface defects and chemical instability. Motivated by the urgent need for green photovoltaic technologies, I explore innovative surface and interface engineering strategies to overcome these limitations.

One aspect of my work focuses on guided surface recrystallization to repair defects and enhance charge transport. In parallel, I have developed inorganic surface passivation techniques that not only protect the perovskite layer from environmental degradation but also improve electronic properties at the interface. Together, these approaches aim to bridge the performance gap between tin- and lead-based perovskites, while advancing their long-term operational stability.

My broader interest lies in integrating material chemistry and device physics to design scalable, lead-free solar technologies. Through this work, I hope to contribute to the sustainable energy transition by pushing forward the practical deployment of non-toxic, high-performance perovskite photovoltaics.
