Background and objectives of activities


For effective use of solar energy, a sustainable energy source, as electrical energy, efficient energy storage technology is needed. However, existing systems combining solar cells and storage batteries are expensive and impractical. Therefore, we aim to integrate photovoltaic power generation and storage using nanotechnology to realize "photovoltaic storage batteries," which can be recharged by light, using low-cost and eco-friendly materials.

Summary of Activities

At present, in collaboration with an automobile-related manufacturer, we are conducting research and development with the goal of on-board "optical storage batteries". Furthermore, by working on research and development together with students, the project will lead to the development of human resources with deeper knowledge of the SDGs and the ability to implement them.
