Diversifying the Renewable Energy Portfolio with Double Perovskite PV Materials

Our team explores prospective materials that can meet the challenges facing the global energy demand for future generations.  We specialize in investigating atomic-level structure and dynamics of advanced functional materials ranging including energy storage and creation. Perovskites are emerging materials that have shown unique physical properties that can be tailored as efficient photovoltaic materials including solar cell applications. Using complementary long- (XRD) and short-range (solid-state NMR) structural methods to unravel the complex atomic level ordering the delivers these functions we are developing new double perovskite high-efficiency, low cost energy alternatives that will diversify the Alberta and Canadian economies.
