Research Description

We are a multidisciplinary team with expertise spanning chemistry, physics, materials science, electro-mechanical engineering, and data science. Our research is driven by the development of novel materials and next-generation device technologies contributing to addressing global sustainability challenges.

The core of our current research scheme is crystalline hybrid metal halide semiconductors, which offer a highly versatile compositional space alongside exceptional physical and chemical properties. By understanding and tailoring their light–matter interactions, we engineer these materials for a range of transformative applications, including next-generation photovoltaics, predominantly metal halide perovskite-based solar cells; advanced optoelectronic devices, such as photodetectors and light-emitting diodes; and chiral and nonlinear optical systems for (on-chip) quantum information technologies.
