Research Interests

I am interested in applying the first-principles methods to study the electronic structure and optical response of low-dimensional materials and design novel functional materials.  Specific areas of interest include novel materials for photovoltaics, such as new perovskite materials, interface engineered organic inorganic hybrid perovskites; the exploration of properties and applications of novel 2D materials, such as phosphorene and TiS3. My current projects include:

  • Understanding the passivation mechanism of different perovskite solar cells at interface.
  • Exploring new efficient passivation molecules for perovskite solar cells at interface.
  • Predict novel perovskite as well as non-perovskite materials for photovoltaics and photoluminescence.
