Solar energy can take a majority of energy supply in our society if we can realize an energy system in which solar energy is stored in chemical substances in the regions with high irradiance and they are transported to the region of large energy demand. For such a system, it is promising to combine high efficiency photovoltaic (PV) power generation and electrochemical reactions to produce solar fuel, which is capable of long-term storage and transport. Our objective is to develop high efficiency PV cells and electrochemical reactors which are included in the system to produce “solar fuel.
The core competence is semiconductor nano-crystals. PV can be twice as efficient as conventional technology by implementing the epitaxial nanostructures of compound semiconductor crystals into the modules with sunlight concentration. Our laboratory develops all the relevant technologies from the growth of nano-crystals to system evaluation. Semiconductor crystals are also important as the active sites of electrochemical reactions. Learning from photosynthesis in natural leaves is important in order to boost an efficiency of electrochemical water splitting and the active sites in leaves are composed of metal oxides, a kind of semiconductor. We aim at high-efficiency production of “solar fuel” by implementing an essential mechanism of natural photosynthesis into artificial crystals. The key exists at the interface between a semiconductor and a solution. Trials are continued to obtain a guiding principle for controlling electrochemical reactions through an interdisciplinary approach between semiconductor physics and electrochemistry.
Furthermore, system integration is our important target including the construction of circuit systems to manage the efficiency-maximum operation point of each element and the backcasting approach to extract the key issues of elements from the performance of an entire system.
