My research focus is inorganic perovskites - both thin film and nanocrystal materials. I work with cesium lead halide perovskites for photovoltaic and phosphor applications. The inorganic perovskite materials should be much more thermally stable than those containing an organic cation, but the phase stability of CsPbI₃, which is the best suited for photovoltaic applications, is a challenge. Through alloying and the synthesis of nanocrystals, I aim to make the inorganic perovskite materials stable in ambient conditions.
