We have to face an energy and environmental problem to build a persistent human being society. The expectation to photovoltaic devices increases year by year all over the world. The aim of our group is to create energy materials through fundamental studies of crystal growth mechanisms.
- Development of in situ observation system: We have developed a technology to observe a crystal/ melt interface at a high temperature more than 1400°C.
- Elucidation of melt growth mechanisms: We study the melt growth mechanisms of various materials including semiconductors, metallic alloys and compounds to build a general theory of the melt growth mechanisms.
- Development of crystal growth technology for obtaining a high homogeneous and high quality multicrystalline Si (mc-Si) ingot for solar cells: We realize an mc-Si ingot for high-efficiency solar cells and contribute to construction of energy-environment harmonic society.
- Creating new materials: We create novel functional materials by metal flux methods.
