Energy Materials Engineering Lab
Machine-translated · View original
A research area on materials involved in producing, storing, and converting energy, such as solar cells, batteries, and thermoelectric materials.

AboutAbout the lab
Exploring materials that generate, store, and convert energy
The Energy Materials Engineering research area covers research related to producing, storing, and converting energy, including solar cells, fuel cells, batteries, and thermoelectric materials.
It is one of the research areas of the International Degree Program in Materials Innovation, and several faculty members carry out research in their own labs.
As a collaborative graduate school, the program also has faculty from AIST and NIMS serving as primary advisors.
The research content varies by faculty member, ranging from crystal growth and thin films to magnetic materials and battery materials.
Key terms
- Thermoelectric materials

*Illustrative imageThin-film solar cells and thermoelectric materials
The lab searches for ultrathin-film, high-efficiency solar cell materials and for thermoelectric materials. It also explores nitride magnetic materials aimed at spin devices and studies current-driven domain wall motion.
*Illustrative imageImproving solar cell performance and analyzing defects
The lab works on improving the performance of solar cells made with compound semiconductors and organic semiconductors. It also analyzes defects in power semiconductor devices.
*Illustrative imageInorganic materials for energy and the environment
The lab develops new inorganic materials, including perovskite solar cells, lead-free piezoelectric ceramics, supercapacitors, environmental purification filters, and low-environmental-impact pigments.
*Illustrative imageFunctional solid-state materials through molecular design
The lab develops functional solid-state materials based on molecular design. It works on developing materials that combine multiple functions, such as luminescent temperature sensing, ion conductivity, and single-molecule magnet behavior, and on clarifying how they work.
