Research Interests

Current research interests are focused on developing novel schemes to improve process transfer from lab to fab, as well as developing robust perovskite materials that are viable for perovskite solar cell/module up-scalability, performance, and cost. In addition, I'm interested in novel encapsulation and device fabrication strategies for perovskite solar cells, perovskite x-ray detectors and perovskite LEDs.
