I first developed an interest in solar energy when I was in high school. I was fascinated to learn that photosynthesis occurs in the plants that grow all around us but with a conversion efficiency of just 3%. I then considered that humans should use this abundant energy source more effectively. Solar power generation is a highly flexible approach for power generation with renewable energy, in terms of the range of locations where devices can be installed. I hope we can contribute to the realization of a system for the local production and consumption of energy.
