Dr. Bayram Saparov is the head of an inter-disciplinary research team that focuses on the synthesis and characterization of compounds with potential applications as energy materials including photovoltaic (PV) and photocatalytic materials, light-emitting diodes (LEDs), superconductors, thermoelectric and magnetic materials. His group aims to bridge chemistry, crystallography and synthesis with physics, engineering and application of functional (e.g., energy) materials. Specifically, the Saparov group focuses on synthesis of novel materials (hybrid organic-inorganic materials, chalcogenides etc.), characterization of their crystal and electronic structures, and physical properties, and if warranted, their performance in actual devices (e.g., in solar cell devices).
