Outline

Photoelectric Conversion Research Team

Lasting supplies of clean energy for our society is an essential challenge to maintain our way of life. The predicted exhaustion of fossil fuel resources and the increasing pressure generated by environmental concerns and climate change have triggered an intensification of research into renewable energies. Solar energy is potentially a sustainable energy source and is a promising candidate for a resource that is CO2 emission-free during use. To help realize the dream of a low-carbon society, our aim is to create unprecedented designs for organic thin-film photovoltaic cells with efficient photoelectric conversion. Our team also focuses on the development of photoactive layers based on structurally controlled donor and acceptor units at the molecular level, and novel methodologies for donor/acceptor and organic/electrode interfaces with high efficiency of carrier generation and extraction. The organic functional materials we develop are thoroughly investigated from the viewpoints of optical, electrical and morphological properties. We will contribute to the development of green innovations through our research.
