Infrared sensing materials are widely used for night-vision camera, range finding, or medical imaging applications. However, commercial materials for infrared sensing or photovoltaic applications are limited in expensive III-V compound semiconductors. Solution-processed quantum dot materials have advantages over the III-V counterparts because of the low cost, large-area processibility and bandgap tunability. Our focus is to synthesize high performance quantum dots for energy, sensor, and imaging applications.

2. Solar Painting Technology
One of our important projects is to realize a solar painting technology. While the concept was proposed decades ago, a paintable solar cell on urban surfaces is still in our imagination. Our goal is to replace conventional rigid solar panel with DIY solar cell for urban applications such as building-integrated photovoltaic (BIPV) or vehicle-integrated photovoltaic (VIPV). For this goal, we are actively pursuing a new field in surface chemistry of nano-particles, relevant device physics, and process engineering.
