Inorganic-organic halide perovskites have opened a new era for low-cost and high-efficiency solar cells in the last few years. They have already shown photovoltaic efficiencies of exceeding 22 %, which is also the highest-performing solution-processed solar cell on record. The unexpected breakthrough and rapid evolution of this family of materials have energized not only the photovoltaic community but also the lighting communities’ efforts to create devices from inexpensive and earth-abundant constituents.
My research focuses on the following topics:
- Synthesis of perovskite nanocrystals for lighting applications
- Understanding the reason of hysteresis in perovskite solar cells
- Wide band-gap perovskite materials for tandem solar cells
