Our current research focuses on high performance, low cost electronic materials and devices including Perovskite Solar Cells, Photodetectors, and X-ray Imagers.  Our interdisciplinary research team hosts scientists with different backgrounds of chemistry, materials, physics, and electrical engineering. We focus on applied research, while we are strongly interested in fundamental understanding of science that enables the applications. 


We have a strong collaboration culture, and nearly all of our projects have collaborators from academia, industry and national labs. We train the next generation of scientists and engineers to help them succeed in a very competitive job market as well as in future careers, either in academia or private sectors. 

Our Current Research Interest


Perovskite Solar Cells

Perovskite materials are arising as a new generation of solution processable metal halide perovskite photovoltaic materials.Our research on perovskite solar cell involves :

  • Understanding the fundamental material and devices physics, mainly the photon to charge carrier conversion,  to explore the theoretically attainable highest efficiency; 

  • Device design, material processing and material chemistry for the record power conversion efficiency of perovskite solar cells;

  • Understanding the physical and chemical properties of perovskites to enhance the stability of perovskites devices;

  • Scalable manufacturing of perovskite solar modules, including single junction and tandem modules;

  • Synthesis of perovskite crystals with tuned defect density, compositions, layer and quantum structures;


Visible photon and X-ray detection

We are interested in developing perovskite materials based X-ray detectors for X-ray imaging and γ-ray spectroscopic detectors for spectroscopy, which is based on our discovery of ultra-long carrier drift length in the strong radiation-stopping perovskites. We are developing

  • Perovskite pixel detectors and array detectors for X-ray imaging. The next generation of X-ray detectors will be much more sensitive, clearer due to the improved resolution, and cheaper.  

  • Perovskite gamma-ray single-photon detectors can give high resolution gamma-ray spectroscopy at much higher operation temperatures than state-of-the-art products, and are 100-1000 times cheaper;

  • Perovskite single photon counting detectors which can read-out photon numbers from scintillators.  These photodetectors are self-powered and operate at much higher temperature than SiPM and PMT.
