Introduction:

Global environmental destruction and climate change problems caused by mass consumption of fossil fuels have become critical as the global population has grown exponentially. Therefore, there is an urgent need to develop alternative energy sources to build sustainable societies.
We are developing innovative technologies for harnessing various renewable energy sources. The energy conversion devices on which we particularly focus are that generate electricity from solar light (solar cells) and solar thermal energy, and that can harvest small amounts of energy, such as waste light, waste heat, and vibration, from domestic and public environments. In addition, we are investigating fabrication methods and process and characterization techniques for energy conversion materials to achieve our main research target.
