Energy harvesting Division

The Energy Harvesting Division will establish innovative energy harvesting materials, and technologies that will contribute to realizing the SDGs and building an IoT society. Energy harvesting refers to obtaining easy-to-use electrical energy from familiar energy sources such as heat, vibration/rotation, light, biological substances, etc. The Energy harvesting Division aims to propose new energy harvesting methods by exploring the principles of energy harvesting and improving its performance, proposing and demonstrating related technologies, and promoting the exploration and development of related materials.

Photoenergy Conversion Division

The Photoenergy Conversion Division conducts research on the development of materials and film fabrication methods for mobile solar cells, research on practical solar cell materials, and material development aimed at elucidating the mechanism of artificial photosynthesis. Through these studies, we aim to develop wearable/flexible photovoltaic battery devices.

Electric Energy Control Division

The Electrical Energy Control Division integrates materials research and device research for SiC power devices, as well as circuit design research, and conducts research that is directly linked to practical application. We will conduct material research, device fabrication, and circuit design for ultra-wide bandgap devices (Ga2O3, AlN) to anticipate future device technology. In close collaboration with AIST and NIMS, we conduct power device research from theoretically based material development to device fabrication and circuit design. Through these studies, we will conduct research covering the development of power devices from materials to circuits.

Molecular Designing of Materials Division

The Molecular Designing of Materials Division makes full use of chemical principles such as catalytic reactions, organic chemistry, and organic elemental chemistry to create environmentally friendly and energy materials. We will build an academic foundation by focusing on basic research that cannot be carried out by companies in the development of environmental and energy materials that are highly needed by society. By studying material functions and mechanisms of action at the atomic and electronic levels, we aim to enable material design and creation that appropriately and quickly responds to the needs of society.

Sub-nanoscale structure evaluation of Division

The Sub-nanoscale structure evaluation of Division promotes cutting-edge measurement research to evaluate the atomic and electronic scale structures of devices. In addition to advancing the unique measurement methods in which the University of Tsukuba has strengths, such as advanced synchrotron radiation, positron annihilation, electron spin resonance for devices, and time-resolved electron diffraction, we will also advance research on the application of these methods to energy devices.

Integrated Fundamental Study Division

The Integrated Fundamental Study Division develops unique basic research such as functional material design through self-assembly and supramolecular chemistry. In addition, we will also promote basic research that has high societal needs, such as understanding catalytic reactions through surface science. We aim to create new fields through collaboration with researchers from other divisions.
