FemtoLab for Advanced Energy Materials4

Today, we are witnessing a explosion of new energy materials that will ultimately replace silicon in photovoltaic and optoelectronic applications. These next generation energy materials are often found to be morphologically complex and structurally disordered, exhibiting region-specific properties. Yet, an understanding how the local variation controls exciton and charge dynamics and affects photophysical properties of these new materials remains unknown. In order to catalyze a new era in the study of new energy materials, we are developing ultrafast imaging technique by combining time-resolved spectroscopy and microscopy. With this advanced technique, we are studying chemical and photophysical properties of wide range energy materials such as organic semiconductors, organic-inorganic halide perovskite, quantum dots, etc on micro & sub-micro length scales and femto to nanosecond time scale.
