Research Activities
My area of expertise is materials science and photovoltaics, with a specific focus on pioneering advancements in transparent conductive oxide (TCO) materials for solar cells. Novel functionalities within these materials can be created through non-equilibrium processes. Materials are designed using widely adopted methods such as magnetron sputtering and ion plating at low temperatures (< 200℃), allowing for seamless integration into solar cell fabrication procedures. My research involves a thorough investigation of the complex interactions between material structure, impurities, oxygen stoichiometry, and electronic properties to fully maximize the materials' potential performance. Furthermore, I collaborate closely with researchers both inside and outside AIST to apply the developed TCO materials to a wide range of optoelectronic devices.
