- Asso. Professor
- Kyushu University, Japan
Toshinori Matsushima received his Ph.D. in Engineering from Kyushu University. After gaining experience as a postdoctoral researcher at several institutions, he worked as an assistant professor at the Japan Advanced Institute of Science and Technology (JAIST). He later returned to Kyushu University, where he is currently an associate professor at the International Institute for Carbon-Neutral Energy Research (I²CNER), engaging in both education and research. His research expertise lies in halide perovskite and organic optoelectronic materials and devices, particularly in solar cells, light-emitting devices, and field-effect transistors. He also focuses on exploring the fundamental mechanisms of light emission, charge transport, and electronic states in these materials and devices.
Research topics
Halide perovskite materials exhibit a wide range of outstanding properties, including excellent charge transport capabilities, high defect tolerance, and remarkable light-emitting performance. Their tunable bandgap, achieved through precise control of film composition, makes them highly versatile for various optoelectronic device applications. Additionally, they are solution-processable, enabling cost-effective and scalable fabrication of flexible and lightweight devices. To further enhance the performance of perovskite-based devices, we are actively developing functional organic materials with outstanding properties through precise molecular engineering. By carefully designing these materials and integrating them with perovskite-based architectures, we aim to create next-generation ultra-high-performance photovoltaic devices, light-emitting devices, and field-effect transistors. Our research is dedicated to improving photoelectric conversion efficiency, charge carrier dynamics, and long-term durability through innovative material synthesis, interface engineering, and device optimization. Furthermore, by systematically elucidating the optical, electrical, and electronic properties of these materials and devices, we seek to deepen the fundamental understanding of charge transport, interfacial phenomena, and degradation mechanisms. These insights not only contribute to scientific advancements in material physics and device engineering but also pave the way for practical and industrial applications. In particular, our research emphasizes solar cell development, with the long-term vision of achieving a carbon-neutral and sustainable society by efficiently converting abundant and renewable solar energy into electricity. By bridging fundamental material research with real-world applications, we strive to accelerate the commercialization of next-generation energy-harvesting technologies.
