Optical Spectroscopy
We utilize in-situ and ultrafast spectroscopy for non-invasive understanding of materials growth, interfacial structures, and carrier dynamics across various semiconductor interfaces.

Optoelectronic Devices
We develop energy-efficient devices for converting photons to electrons, electrons to photons, and photons to chemicals, aiming for a sustainable energy future.
Latest News
Formamidinium lead iodide perovskites were promising for photovoltaic applications; however, water absorption limits their reproducibility. Our collaborative work showed that the solvent dimethyl sulfoxide, widely used in perovskite fabrication, exacerbates this challenge. A capping layer was developed to mitigate this issue without affecting perovskite crystal quality.
