Researcher's Profile

To enhance the utilization of solar energy, development of photovoltaics compatible to various locations is requested. Among various solar cells under development, "perovskite solar cells" are expected as a representative next generation solar cell, which can be manufactured by printing methods to achieve photo-electric conversion efficiencies higher than 25 percent, together with compatibility to low irradiation conditions. To accelerate the practical application of perovskite solar cells, we are promoting the development of novel materials and processing methods to improve conversion efficiency and durability. Since perovskite solar cells are composed of a variety of organic and inorganic materials, the performance of perovskite solar cells could be enhanced by analyzing the properties of each material in detail. On the basis of materials chemistry, we are going to develop light-weight, flexible devices with film substrates.
