[Research interests] Uchida has over 20 years of research and engineering experience about the nano enabled organic photovoltaic. In the case of dye-sensitized solar cells (DSCs), he succeeded in the development of high performance organic indoline dye molecules and proofed over 10%. Moreover he focused on the cell assembling technique such as full-plastic, light-weight, film type as a ubiquitous power source. He is also now showing strong activity of perovskite solar cells (PSCs) based on the scientific interest such as crystallography, surface engineering and electronic device simulation. Recently his fundamental research work elucidated one of the mystery of perovskite which has large hysteresis in I-V curve due to the huge junction capacitance between TiO2 / perovskite boundary.
