Light energy conversion technologies that use semiconductor materials are key technologies for the realization of a renewable energy society. Solar power generation is one of the most important sources of renewable energy. Photocatalytic technologies are expected to have various applications, including serving as an effective way to reduce carbon dioxide as well as generate hydrogen gas through water electrolysis. There is a demand for greater reductions in the cost of solar power, and the conversion efficiency of photocatalytic technologies also needs refinement.

Our research involves investigating power production forecasts, new system configurations, and other subjects based on the analysis of data gleaned from solar power systems. It also involves cutting costs and boosting the efficiency of various types of solar cells, as well as their use as power sources for the IoT. At the same time, we are searching for new catalysts for carbon dioxide reduction and water electrolysis. We will advance our research efforts—which focus on everything from devices to systems—through industry-government-academia collaborations.
